So a chunk in my temporary base just reset, and I have no idea why. Fortunately I had a backup I made earlier in the day so I can rollback or restore the things I lost, but I still have no idea why it reset as it had not really been touched for many many hours. The following had been in the chunk reset, and if anyone thinks they know the cause for this, please tell me.
-Numerous vanilla double chests (10ish)
-Numerous barrels (10ish)
-2 Ender chests, both being pumped out of their contents slowly from another pair at a distant place with a chunkloader
-Floor of xychorium-related blocks (I put this here because I heard xycraft was a bit problematic sometimes.)
So really, nothing.
Ok, so turns out all my other chunks with ender chests AND chunkloaders have been reset as well. Problem solved. Dammit chickenbones!
Also, does anyone know what happens if you use MCEdit with FTB? Does it remove all non-vanilla blocks/entities, does it corrupt the map, are there mods that work fine but others that don't, etc. All in all, is it safe and reliable to use?
EDIT: Huh, when you type in "ender" in the creative menu it crashes. Is this just me?
EDIT 2: Or just "end"
