Continuous spinning on outdoor lamp

In the Jazz in Time Episode (level 2 Colonial Chaos) running Jazz2+ 5.10, Jazz gut stuck in an infinite spinning sequence after pressing down after a running jump, and accidentally hitting an outdoor lamp. This was the lamp to the right next to the first sewer entrance in this level. I didn't find any way to pull Jazz out of this spinning trance.

I was about to upload the image of this instance, but it seems like image upload is not working on this forum as of now.

Thanks. This report refers to buttstomp getting stuck on thin tile masks, neither progressing nor terminating (nor allowing directional inputs, surprisingly).

I am an official JJ2+ programmer and this has been an official JJ2+ statement.

This build tries to fix this bug (only in local games, for testing purposes). More broadly, it tries to fix all interactions with masks that are only one pixel thick, such as the three coins before the fire shield in A Cold Day in Heck, so they are treated as normal floor instead of causing players to fall on them forever. Because this code affects floor detection, it should be tested with things like slope detection, walljumping, and standing the correct number of pixels above floor.
