Iv been having trouble with it.

After compiling and saving some of the polygons change form, like say from "normal" to " doesnt collide" and other stuff.

They don't change form.
Pay attention that when u make a polygon it will have the attributes of the last one u made.To change this, select the new attribute and press "set".

they do sometimes. i have no clue why :(

I am pwned.

lol Demonic as much as Id like to say" omg you were sooo right" the fact is that you arent....they change and they change alot.
