"Missing tile" under transformer

I tend to move around in the same world a lot, meaning I might scum save back 20 cycles and play from there.

This happened again, in the same place, in the same way. When the cycle ended I reloaded the game at that point and the problem cleared up. This is a real bug and not a hallucination.

I can confirm that tiles can and do go missing.  This post of mine goes into greater detail, and it's very hard to actually catch this happening, though its effects can be substantial.  They can also spontaneously reappear even without reloading a save.

Edit: Not sure if this the same bug, as in my case while a tile went missing it was not rendered on the screen, though usually they'd go missing while they were offscreen.
