Kamer put in some work to narrow down an obscure, but somewhat common, bug with "pc exits anywhere." Several players have commented that this quest condition will fire upon teleporting, which for Warm Ashes means provoking wilderness events inside guild halls, shops, and so forth.
He relayed to me his tests and came to one conclusion: "Recalling [into] buildings that aren't capitol cities causes the exit trigger." So teleporting into the knightly hall in Wayrest or in Daggerfall City will not cause it, and teleporting into buildings in Gothway Garden or Warmore (in Wayrest region) will cause it.
When you say recalling inside of buildings, you mean into them, right? Or does the teleport spell trigger it with both anchor and teleport?
Yes, when you teleport inside of them
If you are already inside it won't do "Pc exits anywhere"
But if you are anywhere but the place where you put the anchor it will trigger the exit action
I guess a simple way of saying it, anchoring wont trigger if you teleport within the same building/dungeon as the anchor
If possible, preferable behavior would be to disable this quest condition when teleporting. That would prevent a lot of these odd situations.
