Quoted from genex:yeah i broke a sling plastic and the plastic on the front of the bowling alley came off as well as the plastic on top of the rug.
Otherwise playing well aside from random stuck balls.
The bowling alley - since it determines what you 'roll' based on where the thing is "supposed" to be pointing - mine will sometime stutter and not rotate left and right smoothly. if that happens then it's a random to see what you hit since it may be pointing directly at the pins when you release the ball, but it's 'actually' pointing to a gutter b/c of how it interprets what your roll actually is (if that makes any sense at all)
Have you done the shutter fix?
I had that issue but did burningmans seal and haven't had a missed shot in bowling alley sense.
