omni's map in sm206 not working correctly

There are points in the map where my surroundings disappear and I’m seemingly transported to a buggy place outside the map, but enemies from where I should be can still hurt me. Is it just me?

For reference: https://www.quaddicted.com/reviews/sm206.html

I just ran through sm206_omni on Normal skill in vkQuake, no issues at all.

I should note I’m using the latest QuakeSpasm.

Here is exactly what happens. I’m at this point in the map:

Here, I move forward just an inch and suddenly I’m here:

It’s quite disconcerting. I’ve tried QuakeSpasm and WinQuake with the same result. Reinstalling the map didn’t help.

Heh, I just tried it in Mark V WinQuake and QDOS (edit: and “regular” QuakeSpasm 0.93.2) and yes, I got the same bug in that area, the geometry goes all wrong.

It is fine in Quakespasm-Spiked, however.

Edit: quasiotter reported the same on func_msgboard: https://celephais.net/board/view_thread.php?id=61841&start=8

Thanks, Gila, good to know it’s not just me. I’ll have to try a different engine, I guess.
