Summary
This is a short demo which demonstrates a bug in the design of Memento Mori II MAP16: The Nephilim. Normally, when you run upstairs to the teleporter in the east of the map, you get placed on a teleport pad where a pillar used to be. However, while the tripwires that open the pillar are placed on the fronts of the highest steps (linedefs 1201 and 1214,) they are not placed on the linedefs next to them (linedefs 1175 and 1184.) Therefore, it's possible to jump around the former linedefs, and prevent the pillar from opening. As a result, entering the teleporter will result in trapping you under a door, forever, until you use the noclip cheat to escape.
