I have done 4 playfield swaps with Mirco playfields.
Black hole (bought September 2019)
Addams family (bought April 2021)
Funhouse (unknown date, pre 2021)
Twilight zone (unknown date, pre 2021)
Of these, only Funhouse has had problems - flaking, cracks etc.
The other three are still fine.
Do we know which playfields and/or dates are the ones having problems ?
