[Bug] Removing/Replacing block breaks the world
From friend who caused this:
So ... short hand of what I was doing - I had built a stone container for tailings, but wanted to make it deeper, so dug out a big cube of space under the stone floor. Once I had it dug out I started to line it with stone, when I had filled 2 and a half of the walls + the floor, it all vanished. But hammering one of the invisible stone pieces brings it back. You can now make it disappear by putting a new stone piece down in the area.
I confirm replace/removing the stone breaks/fixes the area. Visible for all players and occurred even after server restart.
So enjoy this video!
EDIT: "Basically if you start laying stone in the area seems to trigger it, definitely if lining the walls
Checked putting more stone on the floor - does it too. Seems that if you remove 2 stone, you can put 2 in elsewhere - and the 3rd one breaks it"
