If you use the normal teleports in single player to teleport to different locations, it will telefrag things: I was testing my map and wanted to see if some monsters are at the correct height, but I couldn't because all the barrels would explode when I telefragged them as a spectator.

Interestingly, the spectator telefrags the things below it, even when using very high height for the Teleport (Z Height), so the spectator is somewhere far in the sky. As a player, it does not telefrag anything (assuming the height is correctly used for the teleport destination.
