I have a Stern Avatar LE. I bought it NIB this spring. It has worked perfectly until a few days ago. When a ball is locked in the Link Pod & another ball enters into the pop bumpers (adjacent to Link Pod) & gets bouncing around it some how registers a 'hit' on the Link Pod. The locked ball is released & multiball starts. To start multiball requires two additional hits to the Link Pod, but the ball bouncing around in the bumpers is registering as hits o the pod! Any ideas? Thanks in advance.
