Why does this mod make savegames crash?

I put together a custom Superhero class, but for whatever reason whenever I try to load a saved game while the mod is enabled, the game crashes to desktop. (I can start new games though). The files for the class are attached.

EDIT:
I tried using the class with no other mods enabled and now it loads, but all of the associated artwork disappears when I load a save.

EDIT:
It still crashes though If I try to load the save after exiting the game entirely.

 

Mods aren't really updated all the time, and it's best to only load savegames with the version of the mods you're using. If you wanna test something, ALWAYS make new games a few times to see if e.g the broken artwork is not actually broken.

 

I HAVE tried it a few times. None of the characters I made using this class will load back up.

 

Doesn't anybody have any insights?

 

Okay fixed it. Rename your Skills folder to skills.
Buggered if I know why this fixes things, but it does.

 

Really? Thanks!
