Quoted from Doctor6:Yep. They sure do.
False - there hasn’t been any issues with the later builds.
Quoted from Only_Pinball:Supposedly they are not even sending the washers anymore
All the new games have black plastic washers under the posts. JJP supposedly ran out of update kits for older games according to one source. But most people just took care of the issue themselves.
Bottom line - new games that have the black washers or older games where the user has added the longer posts and PETG washers have had little or no issues.
