Mystic_Quest

Did have Helgen reborn from the start. Will look into it, mostly ignored that mod until now. I don't trust ENBs at all... with the perfect settings they may offer the best result of both performance and quality but one peculiarity in your machine or a bad setting can make it all go to hell. Anyway, I may have solved the problem... But wanted to wait a while and test it more before posting it into the OP. Changing the load order cured all these afflicted saves and I can load from them normally. Also, the game now doesn't crash on the 22th of the last seed. Every time I thought my game was stable, a problem occurred so I still have a hard time believing it. By changing the load order, a conflict between some mods must have been "solved". Most likely candidate I think was cell resetting. Time will show now.

UPDATE: Got a bloody breakthrough!!! Not found the culprit yet (any ideas?), but hopefully getting close... updated the OP... (sorry for the double post)

Yep, even after quitting they crash on load. I will check out that guide. Unfortunately even if I follow it, it will take ~30+ hours of gameplay to see if this happens again T_T Anyway, thank you for the replies, will update if anything else happens!

Had double these mods on my FO3 and not a single crash... damn Skyrim is too sensitive :/ (if you think the loadorder is scary you should see the gameplay :P) As I play the game the script load probably will be getting larger and larger yes... Is there any way to measure it? Save cleaner shows some statistics of the saves - are these useful - should I post them too? As for the conflicts you are probably right... the general idea is "something that appeared at a later point in the game doesn't like something else". But what baffles me even more is that that something seems to appear in the last 2-3 saves as well. For example I used to load my 3rd from the end save and didn't have any problems. But after I progressed in the game and the crash happened at that point, even that saved game crashes as well, which seems very strange. Next time I mod Skyrim, after I am done with the army, I will follow these guides... this time my eyes can't take much more (even a little astigmatism is a ***** when reading) :( I was hoping to play for a month before I enlist - if you guys come up with anything at all as a possible solution, even if it's just a shot in the dark, I would gladly try it.

Thank you for the reply! These overhauls should be compatible - at least according to their descriptions. But who knows... They don't work if I restart. I have also tried loading a healthy save/new game and then loading these saves from that one. About the mesh theory - what caused it though to CTD in the first place? For example at one time I am at Arcadia's Cauldron and crashed when I used the alchemy table. I restarted and the previous save did not crash after restarting on my first playthrough. I went to Dragonreach instead and crashed there. On my second playthrough I crashed outside of BleakFB. On my second playthrough they always crash on load - restart or loading from a healthy one does not "fix" them. But I am convinced the error is the same is in the first playthrough. Could that mesh be on the character? Why did it not crash when I equipped e.g. the item though? I wear about 7-8 equippable items in slots 44,55 etc - for example a face mask from the face masks mod. If it's not on the character I can't think of any other similarities concerning meshes in the locations I have crashed. Maybe I am wrong on this though and missing something. At any case it is something that kicks in late in the game... kicks in at the time I am starting to get convinced that the game is stable. It's like I am being trolled... Can't I at least have a normal CTD that happens every 10 minutes? (Will be back tomorrow)

First of all, I'll be honest, I did not follow any STEP guides (only recently learned about it). I am throwing this here in case someone can give some insight about what is happening to my game and save me from going to the madhouse... I'll try to provide as much information as possible. What I did:-Used mod organizer.-No INI tweaks, only safe ones which I had tested extensively, tried vanilla INIs as well.-Installed one mod at a time and tested each one extensively.-ALWAYS started a new game, as I know that scripts from mods etc are attached to the saved game.-Testing included waiting a few days in game and at least half an hour usually trying the mod's content.-Reading everything on nexus about each mod and their compatibilities.-Trying to have as few scripts running as possible.-Tried with and without bashed patch (SOT excluded).-Installed memory patch - got confirmation that it works, monitored memory - it doesn't hit peaks (tried without memory patch as well just in case).-Optimized as much as I could, installed only low-res textures, got great framerate.-Stressed-tested it with cheats, 500+ speed across the whole map, spawning various things like a mage army etc.It took me 3-4 full days to install all the mods and make it stable. First playthrough- how the crashes started: After about *20* (real life) hours of gameplay (2-3 days in-game) I had no crashes at all. Suddenly I enter Arcadia's cauldron, tried to use the alchemy lab (that was random) and got a CTD. Tried to load the last save but got another CTD. Tried loading the save before it and it worked. Until I played a little and got a CTD again. Second playthrough- how the crashes started:At this point, I had ditched headtracking, footprints, reneer's crime overhaul, dovakrid dragon lords, birds of skyrim and moonpath.After about *35* real life hours and 6-7 days in game, thinking my game was at last stable, outside of Bleak Falls barrow, my game crashed. After that crash, the last *3* saved games started crashing on load. Nature of the crash:It is random but it's probably not. It seems to happen after a very long time in the game (which sucks). Both times they happened while under no stress at all. Once the crash happens it seems that afterwards I can't even load my recent saves. Notes:-There is no save bloat. None at all.-No orphan scripts with save cleaner.-Crash happens when loading certain games and randomly while playing.-Crash has never happened during area transitions. -Using Fuz ro do'h and OneTweak. Tried without them too. Here's the load order: Papyrus logs: Papyrus log from the first playthrough: Papyrus log from the second playthrough: Here are some faulting IPs of the SKSE log: My system specs shouldn't be of any relevance since memory usage is fine and the crash seems to happen after a long time in-game and without under any stress, but here they are: Any insight on the bloody cause of these CTDs? I am desperate and very very tired... UPDATE: I managed to replicate the crash! Hopefully the solution is nigh! It was simple all along - the crash happens at 22th of the last seed in-game. The game starts at 17th of the last seed. The crash seems to always happen after spending five days in-game. Tested it by waiting in game until the 22th with: -A previous save of the same character -Another character save -A new game INSIDE the Alternative Start cell. "Sands of Time" and "Requiem", to my knowledge, are not activated until you leave the cell. No mods configured, no items taken - nothing. Speculating on the cause of the crashes now... 1)Cell respawning (the crash can happen anywhere you are as it seems and the cell respawning may(?) be a lengthy process which caused the saves on that day to be unusable and it happens no matter your character is doing or where he is). 2)Something gets added to some list on the 5th day - for example an item on a vendor list. 3)Weather changing to a specific weather of COT...? The crash happens in interiors too though so it does not *render* the weather, but it probably registers it anyway. Improbable anyhow. 4)Anything happening independently from the player - like an npc going somewhere or doing something. These only come to mind atm. Requiem and SOT are probably not relevant to the problem, if they don't indeed change anything before being activated. Will update if I find it...
