You would think the spinning disk black residue would have picked up on the test games ? Is it all games, or just a problem with a handful ?

Regarding the lack of QA on the playfields - This is crap ! How many pairs of eyes have seen this problem on the assembly lines and NOT reported it 

The Gene head painted by a 2 year old - Are Stern serious ?? Was this a joke or for real ? I have trouble believing that this was on a customer's game. I wonder how Borg or Gary Stern would feel that SOME games are slipping through QA that have VISUAL problems that are easy to identify.
