[Doom] Monster Teleport Issue (TNT MAP31)
For some reason, it appears that groups of monsters are having a difficult time teleporting in Doomsday.
One example is Map31 of TNT. Near the end of the level, after hitting a switch behind the Megasphere, a bunch of Shotgun Guys are supposed to teleport into the area you are in. However, they take a very long time in actually teleporting to your area. For comparison, in Chocolate Doom, all of them teleport almost instantly.
The Shotgun Guys are inside those walls with the windows in the hallway. They can shoot at you before teleporting (and you can also shoot at them, but you can't actually see them). The only way I can get these monsters to teleport is to shoot into those windows and kill off some of them. When I use IDDT to see them on the automap, you can see many of them walking over the teleport line, but none actually teleport.
I have also encountered this in other maps when groups of monsters that are off-map try to teleport into the room that you are in.

I can't see any issue with the teleporter pens on E1M9 and E3M5 of Doom1.
However, there does indeed appear to be an issue with the Sergeant teleporters on Map31 of TNT:
It seems only two of them are working and only intermittently; the other 4 teleporters don't seem to be working at all).
I wonder if it's to do with the teleporter pens being comprised of single sectors (i.e both sides of the teleporter trigger linedefs share the same sector references). Testing seems to reveal the TNT teleporters have been broken since 1.13.0 (they were working in 1.12.1), the same release the rendering hack support was re-implemented.

I still think there is a problem with monster teleporting overall in Doomsday.
I was just playing Map31 of Plutonia (Cyberden) and I got to the room where you hit the switch to release the first Cyberdemon. It has two Arch-viles in front of the switch. When they see you, both are supposed to teleport into these small rooms behind invisible walls that you can't access, and they will attack you behind those walls. One of the Arch-viles did not teleport into its room, and thus ran up the stairs and came after me. This is the first time that I've seen this happen, but I wouldn't be surprised if I could reproduce it several more times.
