Quoted from TheJerol:Has anyone else had a problem with the auto-plunger after the 0.98 update? I installed the update and now it seems that the autoplunger (which I have set to max strength in settings, btw) barely taps the ball most of the time. Sometimes it fires normally (easily sending the ball around to the left orbit as intended), but most of the time, the ball just sits in the shooter lane while the plunger gives it a feeble tap over and over again.
I had the same problem with my GOTG. It turned out to be a bad node board.
The first thing I would check is the alignment of the auto-plunger prongs. Take a look and make sure they are both making contact with the ball. There's usually a little side to side slop when the playfield is in place. Make sure the ball is centered on the prongs and the shooter rod.
