I started a level, walked forward ~10 seconds, then bots teleported to me and took ~50% damage.
Similar bug was reported by me in “Bots refused to use medkits during Ribspreader boss” topic, but it was “archived”, so I can’t link to it - but in it they died after teleporting, too.
I assume they took fall damage? Why bots can take fall damage at all? They should be immune to it, since the player can’t control whether they fall or use ladders or bug out like in this video.
