Hello and thank you for the reply! I did not get a message notifying your reply so sorry for the delay. I have looked at that guide in quite depth, but the issue for me is that the instructions are hard to see as the pictures require a photobucket subscription, so I can't see the photos the author put up. What also didn't help me out is that the guide is for the old Merge Plugins TES5Edit addon, not the new standalone application. Forgive me if I am repeating what you might already know, but it might just be easier to start from the beginning. So here is the scenario. I use Open Cities of Skyrim. Open Cities has a list of compatibility patches, found here: https://www.nexusmods.com/skyrim/mods/59937/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fmodfiles%2F%3Fid%3D59937&pUp=1 The ones I downloaded and installed, as I also have these files installed too, are the 3DNPC (Interesting NPCs), Legendary, Cutting Room Floor, Falskaar, and Quest Pitfighter patches. I use the updated standalone application of Merge Plugins, not the older TES5Edit extension. I load up all the required files, use LOOT, open Merge Plugins, make a merge, and I get the "there are conflicting Navmesh errors" warning from Merge Plugins. Not knowing how to solve this, I find this tutorial and the link you sent me. It says I have to delete the navigation mesh info map found within the merged mod I made in TES5Edit. So I go and open it up and sure enough there is no navigation mesh info map found. Deciding to skip this step, as I found no info map, I found the post on page 169 of this guide that states that I have to ESMify the master files of my merged mod. The files I needed to ESMify are 3DNPC, Cutting Room Floor, Quest Pitfighter, and Open Cities of Skyrim. So I open Wyre Bash and do that to those files. After doing that, I load open Creation Kit and am torn. Do I need to also activate the all of the merged mod's master files? If so, do I also need to activate the master files of my merged mod's master files? If by your recent explanation, I guess I don't need to activate the master files. The other thing that I don't know is when/if I need to add the BSA files into the editor ini. so that they are unpacked. Do I need to add BSA files if I am merging weapon/armor mods, which I plan on doing too? Again, I am so sorry for not totally following these instructions. I am very new to the more advanced mechanics of Skyrim modding. I was kinda surprised there was no video on this topic to make it easier for us inexperienced modders. Thank you so much for your assistance.
