Techtonica is a first-person factory automation game set beneath the surface of an alien planet. Work alone or in co-op to build factories, gather resources, research new technologies, mold the destructible terrain, establish a base of operations, and uncover long-forgotten secrets.

I just loaded a save and noticed that all of my crank generators were showing the “needs cranking” icon despite them all being on water wheels. Then I noticed that the water wheels themselves appeared to be missing. The crank generators, despite showing the alert icon, seemed to still be producing power.

Looking around my base, I noticed that entire sections of my research core “towers” were visually missing, though when I tried to hover through the emptied space, I was still stopped by invisible cores.

There may be other machines missing now, but those are the ones I’ve noticed so far.

Trying to exit and reload the save did not restore the missing machines.

Has anyone else had anything similar happen? Were you able to resolve it?

In any case, I had just repaired the elevator which I understand is currently the end of the released content, so I’m comfortable calling this run complete and revisiting the game later.
