I wonder if it is possible to use map glitches to, for example, make a shortcut. When the Halloween Spiral 2 was available on the play.hielkemaps.net server, due to server lag I went through the portal in the deep dark level without being teleported. I don't think it's possible, but I didn't see anything about it in the rules.

If there was a shortcut there it would be lag abuse probably

Major Glitches% didn't say you are not allowed to lag abuse so I think it can go to Major Glitches%
