Hi,
I am using shooter template and created a level with many rooms. My character just walks right through all of the walls. It wasn't doing this earlier, but I made some more changes to the level and added some stuff and now even if I do a complete build, the character still goes through the walls. The walls are not marked as being "passable" or anything.
Does anyone know what I did wrong?

Thanks for the help,
Gumby
