Quoted from txstargazer3:
I have had no lockup problems with mine and have never had to power cycle mine, so it seems that it is not all units.
I have never had a lockup or other issue playing it at home. I took it to PAGG last weekend where it was played non-stop Friday & Saturday. I did end up with a big chip on the playfield thanks to a sinking wheel but with that exception there were no lockups or any other issues that I am aware of.
I have ordered carbon fiber protector rings from Cliify (passionforpinball.com, which I think are originally for #TWD magnet protection) to 'repair' my damaged playfield. Besides carbon fiber looks so cool anyway I think they may actually make the game look better. I will post before and after pictures when they are installed.
FYI Make sure your wheels are flush and tight if they sink even a little you will most certainly have nearly instantaneous and heartbreaking playfield damage.
BTW this game is running software version 1.3 which was installed when I purchased it.
