Title Power went out, now unable to load world

Launcher Type FTB Launcher

Modpack FTB Unstable

Modpack version v4.2.6

Details of the issue Not a bug report per se but I'm hoping someone can help me recover from a crash.

Power went out while I was playing Unstable, and am now unable to load the world. Wasn't doing anything in particular at the time, heading back to the surface after doing some mining, although some low end machines were running (endoflames w/ , enderio stirling generators feeding a capacitor, some iron choppers from progression automation). Upon trying to load in the world, it freezes at "Loading World", presumably because the server process was killed, as mentioned in the log.

Errors only: http://paste.feed-the-beast.com/view/de4ddf73

(Modpack changes were updating IC2, added FastLeafDecay, and AppleCore)

I understand no support is officially offered for Unstable, but as I mention this isn't really a problem with the Unstable pack, but a world corruption from the power outage. Hoping someone might have some suggestions on recovering the world. (Backups are too old to bother with.) I have some familiarity with NBT editors if it looks like removing a particular block, or resetting a chunk, might fix things.
