It seemed work fine until a bot killed another bot. Then it immediately crashed. See the attached screenshot. It also crashes when I remove all scripts from the map.

It's caused by some actor hits floor teleport, not bots. It's an ancient ZDoom issue. I made a report over at their forums:'https://forum.zdoom.org/viewtopic.php?t=79174 [^]'

I see, thank you! Let's hope they finally fix it in ZDoom. If not, then either we'd need a compatflag if possible, or the maps would need to be patched individually. The map pack in question will always crash the server when playing that map.

"Actor lands on floor" teleporters that feel a bit more modern compared to the simple linedef-based ones are completely reasonable to expect to work when making a map.

The igpack11.wad is also a classic Skulltag map pack and part of its tradition and heritage.

ZDoom now has a compatflag named compat_teleport that fixes this.

I'm closing this ticket then since we found out what the issue is.
