[0.12.0] Godmode(?) caused by faulty concrete deconstruction

[Ekelbatzen]

I managed to make my character and his inventory disappear:

I was standing on concrete that was built on sandy-grassy terrain that had water nearby (See attached image).
Then I commanded my personal bots to deconstruct the concrete, there seemed to be a random chance
to spawn a tile of water from the concrete tile and then it would disappear again when a neighboring tile was deconstructed.

If I happened to be on a tile that became water I enter this new state.
