MQ Shadow Temple soft lock (not randomized)

[Volpeony]

Been playing Master Quest without randomization for a few days.
Entered Shadow Temple, saved, quit out, and came back the next day. When I returned, I did not receive the standard text popups that said to make use of the Lens of Truth, or to point the bird statue's beak at the proper skull.
Checked the skulls in the first room, with the bird statue that you have to spin, and two of them were real when viewed through Lens of Truth. Tried pointing the statue at either and/or both to no avail. At indeterminable intervals (possibly on exiting and re-entering temple? and occasionally on pausing/unpausing), the skulls would change. Even when there was only one skull that was real, pointing the bird statue at a lone skull would not solve the puzzle.
