i've just found a bug which caused some 3ds models to not be loaded at all. some of you may have noticed it. anyway, the bug turned out to be caused exactly by something i had suspected months ago, maybe a year ago, but i only bothered to check it now. also, the code to correct it was already written by me but i had remarked it out to put something else in it's place. maybe someday i will explain to you why i'm so strange sometimes :D
