A clear and concise description of what the bug is.

While NDCP2 is known to be buggy, there is a certain issue with its MAP21 that appears to be GZDoom-specific. In the first outdoor area, stepping off the floor and into the void will not instantly kill the player like it should - instead, the players simply ends up being stuck in the void, unable to continue. In PrBoom-Plus v2.5.1.4, the player gets instantly gibbed instead, which is correct behavior.

Steps to reproduce the behaviour.

Explain how to reproduce

1. gzdoom -file ndcp2.wad -iwad doom2 -warp 21 -nomonsters +"warp 1720 -2080"
2. Step forward into the void
3. The player is not killed, but becomes stuck instead.
