A few hours ago I noticed in the log of my ftb world it kept spamming that the save was being accessed from another location and it was aborting. This happened in an earlier world and I thought the world was corrupt, because it didn't save anything I did, just my inventory. I did a test by pillaring up with blocks and relogging. Sure enough, the blocks vanished, from the world and my inventory. I'm running monster 1.1.2. I hope someone has a solution. Thanks
