Here's a feed of edits to the Iowa Pinball Map going back to 2019.

"Action button not working. Ball stuck somewhere as it was in play mode but no ball at the plunger. It was fun while it lasted." Godzilla (Pro) (Stern, 2021)
"Quarter mech issue has been resolved.
The mech was a bit out of alignment with the left slot, so the issue was intermittent.
Reseated it and adjusted the spring arm to keep it in place.
Will check on it again soon, thanks!" Seawitch (Stern, 1980)
