Thank him actually, because I didn't know at first til that guy told me, but I'm gonna always put it in every compressed mod just so that people aware that compressing alone is not enough to prevent crashes

I suffer from the game getting crashed without getting that notorious notice of "too many indices" (it just minimizes to the desktop and can't get back to it), looks like several of my high poly w_model are the real culprits, thanks for the tip.
