Crashing on world load

[wafflewarrior64]

since I updated the mindcrack pack, my world will not open. This is what the crash logs have been saying:
---- Minecraft Crash Report ----

Also: Loading any other world works just fine. I'm hoping there is a fix for this world, because I have been working on this one for weeks, and not even the backups will load on the newest version.

that happened to me. I think it's something the game doesn't recognize in the mods. I had to delete the world :C

UPDATE: I downgraded to v6, world works again. A fix for v7 would still be appreciated, I like to keep my mods updated.
