Summary
When tying to play on an arcade machines, and casino machines, the UI bugs out, you can’t play the game and it just throws you off the game (casino machines you get stuck in the seat). The UI elements start to stack up on one another and creates a mess.
It does NOT affect the pool tables, its the only thing we can play together in the arcade.
