Title should say it. My ski-box doesn't connect to anything. (or at least anything it should connect to) How are (for example) bumpers attached to the body but able to fall off? Also, when I load the Wagon JBEAM into BNEditor it doesn't show up and removes any triangles and beams from sight. (Don't mind the fact it's glowing or something.)
It won't load into the editor because of the vehicle controller part, it's in the upper part in the jbeam, it should work when you comment that out.
