Pessima bug

alright, this is with my mod WBIMP, but i have absolutely no idea whats happening
the pessima seems to be using the old pre-update body, despite nowhere in my files is there custom pessima body using the old model in the .dae or is it entered in any jbeams.
cleared cache and every other normal step, but nothing seems to be working.
i do have a jdm body, but it just uses the already ingame pessima body- and besides, it affects all pessimas, whether they have mod parts on them or not.
really weird.
i can send over the file to someone who knows what their doing, and i can trust.
thanks for helping

 

i had this with the miramar, try verifying the game files in steam

 

it just keeps getting stuck on 0%
no matter how long i leave it for

 

please people
this still isnt resolved
