(Note: i was playing the pre release for 3.0.) So, generated a new world (super flat) and I had trouble finding an NPC village. I wandered around some and eventually found one. Since I was in creative, I searched for emeralds to do some trading. Than I noticed something was terribly wrong. I entered the village from the side and saw the sides of a house were gone and so Was the insides. The gardens were ripped up and the blacksmiths place was broken. The lava was pouring out from the sides and some houses were totally demolished except for the doors! I couldn't have been using any mods because I don't think any are out for that version. I still have no clue what is happening in my worlds. I'm NOT making this up. Also in servers nothing weird has been happening like this. Only in solo.
