I'm making an adventure map, and I've been using MCEdit to delete chunks around a floating platform. I tried teleporting (edit: in-game with /tp) 300 blocks away (ungenerated chunks) to build another area farther along in the minigame, but then my game crashed, and I have no idea why. Looking at the console (and observations in-game) it appears to be caused by my teleportation.
I've been using tellraw, scoreboard, attributes, section sign in command blocks via NBT editing, and various MCEdit filters/block deleting (mentioned above), though I don't see how my usage of any of these things could have caused this.
Here's my crash log:

Yeah, it's corrupt. I'll make a backup and try some chunk stuff in MCEdit. Fortunately, I have another backup, but I did a lot of stuff in a short time after it. From now on I'm backing up frequently!
If it matters, here's the crash report, though I wouldn't be surprised if it's just a duplicate:

EDIT: 1,000th post!
EDIT: It seems to have something to do with how I was deleting blocks in the default world to simulate an empty void world in that area. I tried deleting the far edge chunks, and it worked (!), but going to another edge chunk still crashed. I deleted them all now. Let's see if it'll work...
Okay, that didn't work... I tried reducing the world to the chunks that I had built in, deleting the natural terrain around it, and the game "crashes" each time. The odd part is that the game doesn't close itself. The console spits out a crash report, but the game hangs on the "Loading World - Building Terrain" screen. It also doesn't act like any other program when it freezes up: it's perfectly "responsive" even though the console says it crashed.
Here's the crash report:

Anyone have any tips or am I stuck reverting to my older backup and figuring out what I had and hadn't done yet when I made it?
I'm not so familiar with McEdit but I'm pretty sure there's a "repair world" option somewhere. Look for it, and let me know if it works
Actually, it seems that when I go in and it gives me this odd error, the "Player" section of level.dat is gone for no apparent reason. Does this have anything to do with it? Also, "Region Repair" doesn't seem to do anything.
Good news! I was able to port most if not all of the current stuff from the corrupted world to my older backup with MCEdit. Even though I fully recovered from this, I'd still like to possibly know what caused it and what to do if it happens again and I don't have a backup for whatever reason.
I've been using tellraw, scoreboard, attributes, section sign in command blocks via NBT editing, and various MCEdit filters/block deleting (mentioned above), though I don't see how my usage of any of these things could have caused this.
