i have a problem when the game reload a map new or old .the game crush the map does not load so when restart the game automatly bug and exit . The only way to play again is to change the game to keyboad enter the map then exit change again to controller and play until i go to the new map and bug again.i feel like the problem is the map does not load with controller interface for some reason i dont know what to do i cant change contoller to keyboard and restart the game when i go to new map
