Did some playing around and found that the game does not crash while using the Health, Armor, Money, Or Weight. It Crashes all the time while using Super Clip and sometimes while using Super Ammo on some of the weapons.
I actually figured that out before, but I dont renember correctly anymore... I havent played the game since the last 2 patches, but the bug existed back then as well. If I renember it correctly it seemed to be bugged when using both super clip and super ammo at the same time. And it depends on weapon as well I believe (maybe). But I couldnt use super ammo with super clip, so I just used super clip I think. Maybe it dpeended on how many wepons you carried and HOW many weapons you used "superammo/clip" on as well... Sorry I can not help you guys, but I just cant seem to renember anymore.
PS: After thinking some more, actually I think you arent allowed to switch weapon as soon as you used the superammo/clip. So do NOT walk over another weapon since that will crash the game...
Weird that the people working here at cheathappens havent found this bug with their trainer. BUT its such a small bug it dont really matter.
