If you exit a building that was on fire, then sometimes the character ends up on some inaccessible area, far away. This might be because the building is destroyed while you are inside so that the entrance doesn't work.
This happened during normal gameplay when I entered a building shortly after a tree near it was struck by lightning.
I tried to reproduce the situation with torches, and recorded it a few times:
Steps to Reproduce
(a) Set the building on fire. (If the building can't be entered while on fire, set something near it on fire.) (b) Enter the building. (c) Wait for a short while. (Possibly wait for the building to be destroyed?) (d) Exit the building.
