I was going to change design of my parkour, suddenly my friend ask 'why the geyser not working, I can't do this part' and even I replace the geyser, it does nothing.
Same goes for Mr.Granicus, his fire trap at his Burger Course not working as well. (We've tried replace)
The problem is, when we put it into another realm/room, its working but at our parkour, its "sleeping".@SirKewberth
