My game is crashing... Randomly Thread - Call of Warhammer: Beginning of The End Times mod for Medieval II: Total War: Kingdoms

Hello there, after a while of playing the campaign as Reikland the game became literally unplayable as crashes are occured randomly (the one that says chaos has doomed the world) and those crashes both occur on the battlefield whenever i sit there for like one minute and randomly on the campaign map two times when i was closing the city recruitment menu the other time when i was checking one army just by clicking on it. Of course i applied the 4gb patch without it the mod was unplayable for me but really it bothers me now that i get some issues when i'm in the middle of my campaign. Please help me fix it
