Could be my game is bugged, I've done everything you said. I tried playing the normal map of Fleetwood that has boats, I cannot use those either. I was going to see if they worked outside of scene edit and if they did then run scene edit to look at it.
I'm having another problem with my siege map. When I save it over another map and copy the codes over, I get in game on the map and the size is all messed up. All my props are off to the side of the map or over water etc. How can I fix this? I tried saving it over a Siege map and a Deathmatch map.
