I just delivered the game to my nephew. After a few games, the same player shoots again lights, one in playfield and one in back box, blinks with the score reel as it scores.Also the special light on the out lanes blinks too. I forgot the schematic at home. Any thoughts where to look quick? I'm thinking on the advance unit? FYI once you hit the four drop targets the first time it sets double bonus. The second time it sets the same player shoots again. Third time is special light on one of the out lanes.

They are the stock incandescent bulbs. I always take it apart for transport. Unfortunately I had very little time there to troubleshoot it. It could be the extra ball relay needing adjustment perhaps. It was playing fine until I manually hit the drop targets down twice to show my nephew how the same player shoots again feature would work. After that the light issue started. Note that it does not actually give the extra ball just the light issue. I'm sure it was from traveling for sure. The problem is they live an hour and a half away. I want to get back there asap to correct it! I'm sure it's a simple fix.
