I am insanely confused right now. I was gathering some materials, doing my thing, when I noticed that a long hallway filled with chests suddenly... ended where it shouldn't have. I built it to be ten chests long, but for some reason, it suddenly only went to seven! I had another hallway right beneath it, ten long as well, and it too was only seven chests long. It was as if the game thought nobody had built from there out - it was just smooth stone.Well, I tried logging out and back in, and it got waaaaay worse. I (and the base) was underground, and I spawned me above ground when I logged back in. Now it's as if I had never been here! Everything - and I mean everything - is just untouched where I had built. And this seems almost... instant. My whole base is gone, as if I'd never been here. The portal I used to get here is gone. The house I started building is gone. My garden is gone. And I don't think it's griefed - it was way too fast, and I was here! Not to mention the landscape went back to how it was, and covered with snow even though it hasn't snowed.I'm so confused. What in the world is happening?! The only thing I can think of at all is that I'm pretty far out from base, but why would this happen? It's not the end of the world, but if this is going to be a reoccurring thing, I don't know if I'll continue playing past another random wipe. Halp?
