Bugs
When the southern lift to the plasma gun room (sector 96) is triggered, an invisible polygonal region within the upper chamber simultaneously behaves as a lift, separated from the actual lift by an impassable line. This causes a huge HOM if you fall into the "hole" while the lift is lowered, though you are not permanently stuck.

The supercharge next to the yellow key can be picked up without lowering the inner steel platform (e.g., if one has pressed the red switches in the wrong order).
