So, ive been struggling with getting a custom map to be played in the actual KF2 game. I never had trouble for KF1 but for some reason now every time KF2 loads up the map I just made, it crashes immediately. After scouring the internet for days, the only way I can find to make it work is if I delete the UnrealEd.u file, which does not make much sense to me. Can anyone help me?
