This bug mostly occurs in the rooms with the low wooden ceiling, and with a chest on top of it. It may have a light source in the center, and it may not. World type=default, seed -7069629125945563225, it only occurs when you first generate the stronghold, after a world reload it disappears. Sometimes the room may not generate in a stronghold.

In the 3rd screenshot, the light source is not there because I reloaded the world.

This happens when you have a light source and you downgrade the world to a version where the block for that light source doesn't exist.

E.G. Shroomlight when downgrading to 1.15.

Can confirm for 1.16.5

Affects 1.18-rc1.

Affects 22w15a.

Cannot reproduce in 23w18a, the torch generates always where it should be:

Example seeds: 954286524255137287 and 2882857347260676688

Confirm fixed in 23w18a. Code now properly places a wall torch instead.
