I dont know if its just me, but i seem to have had blocks revert a couple of times recently.
the first time i noticed, was 2 Emerald blocks in a door, and CJ replaced them, tho he had no idea where they had gone. Logblock showed that they had been placed, but never showed that they had been removed.
Now tonight, i discovered a spawner, and as usual i grabbed all the mossy cobble, and placed beacons to be able to find my way back. but 5 min later i couldn't find my beacons.
i eventually found the area, only to see that my beacons were gone, lighting removed, and the dungeon was back to untouched.
here are some photos of the logblocks of the areas effected.
note the chest in the background, tho logblock says it was destroyed, and the same with the mossy cobble flooring
i had darky come down to look at the issue, but he was as mystified as i am. any ideas on what i should do?
