For some reason, the textures for my map are showing up in Radiant, but they are not showing up inside of my map. Why is that? I can't see any walls, wall weapons, floors or anything. I tried to compile the map, a bunch of times but it doesnt seem to help. What's going on?

P.S. - ALso my knife damage doesnt work. like wtf, why is all this going wrong D :<
