Quoted from stpcore:
I believe the Premium playfield dates that went over seas started in June. That said, I'm not sure if these Premiums that are being received and unboxed overseas right now will be an accurate indicator of any changes that were made regarding the playfields. The domestic (US) Premiums would be a better indicator in my opinion.
Premiums being unboxed now are definitely older playfields subject to whatever issues they come with. All the guys who have been waiting in the US are probably in a better position as they will be getting updated playfields.
That being said, I'm doing whatever I can to stop the airballs. I know this is not pretty but it works. I butchered up one of my Arwen ramps, lol.
