A few weeks ago before Thanksgiving I was bulding a cathedral on my planet. The next week I went back onto starmade and found that part of my cathedral was missing. It looked like I hadn't even built it. I fixed it and thought nothing of it. I was annoyed but it didn't seem like a big deal. For the past week I have been adding to that cathedral. I had been on this morning and everything was fine. This afternoon around 5:00 I went back on and found several large holes in my planet. They were big cubes of the planet that weren't there. A good deal of the work I had done for the past month was also gone. Not completely but large parts were missing. So my questions are 1. What is going on? 2. I have a backup from before the problem so where should I look for it? 3. and once I find the data how should I put it back into the game. I don't know if other people have experienced this problem but it might be likely.
