someone with some technical experience with DF could you help me understand why i am getting a crash to desktop when my units are loading after going out on a raid this has been an issue i am unsure what the culprit is.

to preface: i was using an older version of the mod (ver 1.15) in a existing save
updated to 1.32 (using the same world that was using 1.15)
no problems at first and the body parts have been changed (hand and foot to claw and claw respectively.

however the game is crashing when it doesnt know what to identify certain body parts as (i assume)

here is the errorlog from the ctd

I'm not expecting a solution per se but would like to know if there is a workaround or way to fix this so that the game wont crash to desktop when this error happens
