Okay so before the latest update like last week or so my attack of the B team worked perfectly fine but now I cant get onto anything not single player or multiplayer it just crashes and says "Exception in server tick loop" and I know that I probably need to allocate more or less memory but I've tried every amount of RAM I can allocate I have I have 8g of RAM and a like 640 graphics-card on my computer I don't know if that helps.
PLEASE HELP AND THANK YOU
