MantisBT - Zandronum
One method found is running at a certain wall that is at a certain obtuse angle. Your player gets locked in the angle, so your view stops jittering left and right and instead bobs up and down as if you are running normally. After a few seconds, you can go through the wall and outside of the map.
Another method is using a player to assist you in getting through an impassible linedef by running alongside him while he is standing still, and with an angled wall on the other side. You will pass through the linedef in a few seconds.
For method 1 (angle):
1: compat_plasmabump true
2: Goto BUG 1
3: run forward at the angle that the red arrow points to and get it so your player stops jittering left and right, so that your view is instead bobbing up and down as if you are running normally.
4. If you do this correctly, you will 'break' through the wall in a few seconds of doing so.
For method 2 (grate):
1: compat_plasmabump true
2: Goto BUG 2
3: You will need either another player or "summon doomplayer" on the green square.
4: Run on the blue square in the direction the arrow is pointing at, while alongside the other player.
5: You should break through the grate in a few seconds if done correctly.
(if you have trouble with this one, try reposition both the green square and blue square player slightly)
These two bugs seem to happen ONLY on zandronum with compat_plasmabump enabled.
The only other port out of (odamex, choc & vanilla doom, zdaemon, gzdoom, zdoom) that has at least one of these bugs is zdaemon. Zdaemon RARELY can have the grate bug (0000002) happen.
