[1.6.2] Error spam on occasion with annihilator turrets

Started a skeleton annihilator, and the starting dungeon was fine. Entered Heart of Gloom, and I get spammed with that error about 6 times each turn once I place a turret down. It even persists when the turret is gone.

Restarting the game doesn't fix it. Rezoning seems to temporarily fix it for the first turret or two, but the errors return.

I think it's not turrets, it's sling-skirmisher related.
