this i understand i had skate 3 when it came out so there was no collision it came with an update and the glitch sets us back before the update but something is letting us merge anyway now but this glitch is random so i am understanding?
Okay so I randomly just tried it again after building a park and then playing some skate 2, and it worked, what do ya know, i guess it is very random. So if it doesn't work for anyone, just try and try again.
