Quoted from BrianJ1337:
I imagine that the amount of bad play fields with the issue is actually fairly small. They’ve shipped 100’s already and we’re only hearing from a vocal minority. They have every right to be vocal but the ones having no issues are probably enjoying their game not posting how perfect their playfields are either.
Aside from maybe the very initial ones made with long-cured COVID lottery payfields that sat extra-long in the warehouse waiting for the line to start, they're likely all affected. The kind of damage these are showing are not the odd defect, but a systemic problem with the way they're being made. I think a lot just haven't noticed since some of these posts are out of the way areas that you don't notice without looking specifically.
But the fact that this same problem has been substantially seen across THREE JJP RELEASES in a ROW is not a good sign that this isn't widespread.
Also the fact that JJP's new customer-hostile policy is just buying back machines rather than fixing or shipping a spare playfield as they have before says there was potentially a large financial hit by taking care of the affected parties for jjGnR the way they did on Wonka and jjPotC. Don't like our defective playfields in our new $11k machine? No GnR for you!
