Remove all those extra mods then install 1 or 2 at a time until the crash reappears.
You just don't throw everything into a pack and hope it works>_<

Well i know it works on single player and it worked about 2 days ago so i was more kinda asking if anyone could tell me if any of those mods are clientside, hence causing the crash... but thanks for the reply.
