During the recent cleaning, after removing the habitrail on the left of the playfield, I noticed one of the plastics was not straight. Worried the stress might cause the plastic to crack, I investigated.

You can’t really see it, but you could feel it (if you were here before I fixed it) this plastic is not straight

Removing the top plastic and lifting up the next layer, one screw is not all the way in, leaving a nut raised from the post, causing a push against the top plastic
