Running Mindcrack pack in an established world with no issues until recent spate of crashes.
Problems started after forcing computer shutdown (i.e holding the power button in) due to another program freezing everything. FTB was running with the world loaded when this happened.
Upon reloading, every chunk containing an enderstorage chest has been reset to the default state (that is to say the one the world is in upon generation) wiping out much of my base. The base has been repaired, but any attempt to interact with enderchests, including but not limited to:
-searching "ender" in NEI
-attempting to open chests
causes the game to suffer a tick issue (can get a crash log if needed) and crash. Provided I stay well away from the enderchests everything else is running as expected, and the game is as playable as ever. So far I have redownloaded the mod pack, but this did not solve the issue.
If anyone has suffered similar issue or has an idea on how to solve this I would be greatly grateful, as they are a key part of my mining/sorting system.
