Tldr: fixed by hex editing. The issue was the map was compiled using win95/98, and they can’t recompile it without potentially introducing a bunch of other bugs. So he was able to hex edit and fix the animation in that screenshot.

I’m not a bot. And I saved like a bunch of words.

We can thank Danny O’Dwyer and the team at noclip for this!!

I don’t think I would consider this “fixed” since it changes the animation. It’s more of a work around but I feel like this is the best it can get without materially changing the level or game.
