I had similar weirdness with mine a long time ago, and the culprit was the connector for the relay module under the playfield. I replaced the connector and everything was fine. Of course all of this happened while the game was part of a temp trade. Trades and pinball shows seem to bring out the gremlins.

^^^ yes, that’s the one.

The best advice I can give is to start replacing connectors until the problem goes away. Connectors have been the culprit for at least 75% of my many early SS headaches.

I thought this was a typo, until I saw the mushroom shape. Thanks for that Vid

I don’t know, man. Will the shiny dimple-proof hardcoat play the same as our Bally tuff-coat playfields? New rules would be cool, but I love my old warhorse of a game.
