Quoted from John_I:

Wow that video sure is revealing. What a rookie design for the posts. This not the whole problem though; this is just an idiotic design for the post holes that makes the problem with the clearcoat pooling and artwork de-laminating even worse.
JJP should fix the design and drill the holes properly as noted in the video. My suggestion to people who own this game is to remove these posts and add a small ring of heat shrink around the shaft above where the threads go into the T-nut, and then another over the first one and another until the post barely fits back down into the playfield to be screwed in. You need to eliminate as much play as possible. Someone who owns this game and a 3D printer might be able to make sleeves that will serve this purpose. Or maybe there is some nylon tubing with the right inner and outer diameter that could be cut and slip over the post and just barely fit into the hole to hold the post snug?
