Unboxed my premium over the weekend and I keep getting random ball saves activating and a new ball plunged when my original ball is clearly still in play and never drained. This only happens when ball save is flashing, so I am wondering if it's a trough sensor issue? This is probably not game specific, but I couldn't find a answer to my problem elsewhere. What should I look into for troubleshooting? Newer to the hobby so forgive my limited knowledge.
