I'm not sure if it's a result of the new patch or not, but for some reason I can not add collisions to objects in map maker. Well, I can, but when I test it, my character runs through the yellow box like it's not there at all. I can check the little box to make the object completely solid, which works, but adding a collision by hand doesn't. I'm not sure why this is, I don't recall having this problem in the past.
I can make everything solid I suppose, but I'm certain people with winged characters will find it quite annoying when they can't fly through tree tops (I hope to make a jungle map, so....lots of trees). o___o
