Fallout 4 mods re-install after loading save file, everything becomes unequipped, fists are equipped, weapon mod quests reset, pipboy becomes invis...

Merging mods gets tricky..... If the mod also loads a bsa, or ba2 file for its assets..... then you would need to rename those as well, to the same name as your merged esp file, but, if you have multiple bsa/ba2 files, things get more complicated. There is likely a video on youtube for just such an occasion though. :D

found out about this merger,

and I was wondering how do I create an .ESP inside it?

I followed video tutorials which just say to "copy" the ESP, then hear something on their keyboard get clicked, and they don't tell me what hotkey combination they used to copy the ESP to the clipboard, so I tried going into explorer when I built my merge... no ESP... this is very strange.

Just zipping them all up into an archive isn't going to make a difference.

 

Have a gander at this video.
