EDIT: Deleting the two mods that altered the Sequin Dress and Agatha's Dress somehow fixed the problem ---- I still don't see how a texture replacement could cause a crash, but it's fixed anyway. Delete / Ignore this, please.

At first I thought there was something wrong with containers in general, but after loading, crashing and loading and crashing for an hour or so, I finally figured out what causes the crash (although I do not know why, exactly) ----

Whenever I mouse over the Sequin Dress (or Agatha's Dress, which in the vanilla game IS a sequin dress) the game crashes instantly. I can move items from my inventory into a container over and over and over with no trouble, but the second the cursor lands on the Sequin Dress or Agatha's Dress, BOOM, crash.

With my limited modding / Fallout mechanics knowledge, I assumed that this happens because the game is missing some information about that item ---- it cannot display the small picture of it, or whatever. It's true that I had a mod that changed the sequin dress to Black, and another mod that swapped Agatha's sequin dress for Irma's feathered dress.... but as near as I can remember, I never had this problem BEFORE; even have screenshots of me in the (modded) black sequin dress.

I'm running 120-odd mods, many of them clothing / texture mods or settlement mods. As noted, I have the two mods that alter the sequin dress. I suppose I can uninstall those mods and see if things get fixed, but I'm not sure what changed from initial install to now. I suppose when I installed the CBBE body, and the associated versions of the 'regular' clothes that maybe, somehow, something got changed? Maybe the game cannot Identify WHICH sequin dress to use? I would have thought last-installed is the winner in any challenge between data sources.

Anyway, if there's a simple way to fix this, I'd appreciate knowing it. I should have just left them in the 'defective' container but I used a TAKE ALL option so now they're in my inventory, where they're even MORE likely to cause me to crash.

Maybe the texture mod is not done properly. There are changes how FO4 stores the texture as compared to skyrim.
