PCS conflicts with every mod that changes landscapes in that zones. It happened to me with verdant when i put verdant esp after pcs esp. Verdant grass blocked courier and guards, courier stayed out of his home days and night. Poor courier that feared grass. So if you want PCS you should place esp at very bottom of load order.
In my game I corrected the bathing esp and works immediately. With requiem the problem was a bad interaction between bathing and atronach stone. It appears immediately at Helgen on general tullius. It happens with revenge of the enemies too.
It's bathing in skyrim. It happens for me with requiem. Look at the bugs in bathing in skyrim page, requiem npc blue glow. You can find the solution too.
Elisif is included in Inhabitants of Skyrim too. https://staticdelivery.nexusmods.com/mods/110/images/23755-1-1354989917.jpg found in images section of the mod.
Good Elisif replacer, UNP compatible are Toccata as Elisif or BTRH Waifu. I prefer and use Toccata as Elisif. BTRH Waifu is here https://www.nexusmods.com/skyrim/mods/53152/?
It's frostfall. In the MCM menu you should untick "Disable Waiting while Outdoors". You can disable fast travel without problems but if you disable waiting you lose some health.
You can try to restore cmd.exe, probably get corrupted, it's rare but... Go to C:\Windows\winsxs e search for cmd.exe then copy it in C:\Windows\SysWOW64 (make a backup first of the original). Sorry for my horrible english.
Ah, you're right. I had an old version of LOOT. Updated yesterday and works without problems. You should follow GrantSP'advice and move MO outside program folder and run every executable, skse, tesv, loot, fnis, mod organizer, as administrator.
