Game crashes (save attached)

[3combined]

Game runs extremely slowly then crashes a few turns of fighting into the current save, logs contain stack overflow with long seemingly circular stack trace. If i wish for geno:soupsludge the lag doesn’t happen, but when I move downwards a few times the crash happens anyway.
Mods: Clever Girl, Careful what you wish for, mark items for pickup (still crashes with these disabled)
