My GOT playfield inserts started sinking after 40 plays... Long story short, Stern is not going to replace it (surprise, surprise). Stern rant over. The real question is what should I do to prevent damaging the clear around the inserts? The inserts are sinking, so the damage is starting to show. I'm hesitant to try and level them on a newer game. My understanding is that the routered lip that the insert sits on is too low. I've also considered purchasing a plastic playfield protector to avoid damage. What would you guys recommend?
