well it's not just with one building. the player is able to walk through anything, trees, decorations, buildings. and for soe reason it only happens when I start placing bots (its a SP map).
Even the bots that are on the second floor of a building will fall through the floor and be able to walk through walls. but the weird thing is 20 seconds into the game it fixes itself.... LOL.
and I don't exactly have Buildings. you see I'm making like an old run down town with bomed out buildings and sftuff. DFX doesn't have any half destroyed buildings that are big enough so I made some out of old ruin pieces.... so in this case the buildings are made of decorations. I thought this might be the problem but I had this same problem in 2 other maps.
Here's some SS to show what I'm talking about. man I didn't wanna show it yet but oh well. Enjoy Spinney LOL.
