I'm applying to make this an official term. LOL
For me, this applies to my GodZilla, but I know of another person with the same issue on DeadPool.
While I'm playing my Godzilla my playfield is slowly moving to one side of the cabinet. This means my plumber is no longer centered and my ball will no longer launch cleanly.
I can remove the lockdown bar and recenter the playfield and it stays put for a short while but it doesn't last long.
Anybody else experienced this it have a solution?
