Hi. I've been playing on a single player map, Cake Defense 2 (http://www.ocddisco.com/2013/05/cake-defense-2/), and everything's been going fine for a few weeks playing it. However, I went to play it tonight, and when I went to join the world, Minecraft crashed. I restarted mc, and when I get in the world, half of it was just missing (half of the part I need anyways). I have no idea why it did this, but I'm hoping someone has a clue why this happened, and if it's possible to fix it (not having to reload the entire map and play through to level 21/24 again).
Sorry, I don't understand a lot of technical stuff, but here's one log I took (set to expire in two weeks, I can make it permanent if desired) http://pastebin.com/fXCEDG63. As requested, here's my computer specs (also set to expire in two weeks) http://pastebin.com/ikYSeBFD. I'm using Java 1.8, and I think I'm using 64 bit.
Additional information: Since I downloaded the map I've played it numerous times, and in between I've switched "profiles" between DukeofHoth (1.5.2) and OptiFine (1.8.4 w/ Optifine). Also, the last time I went on the map I was messing around with fireworks, which I was placing in chests. Not sure why either of those things would mess with it, but I thought I'd mention them anyways. Thanks for any advice you have- if there's anything else I can do to help you, let me know.
Based on the logs you loaded your 1.5.2 map into 1.8.4 then loaded it back in 1.5.2; any world loaded in 1.8+ is not compatible with any older version due to changes in the save format, even though they can still see and try to load the world since the changes were only internal (1.8 changed the way item IDs are saved, using names like "minecraft:diamond_sword" instead of 276, which causes an error when 1.5.2 tries to read a string as a number, thus the "Reading NBT data" / "ClassCastException" errors in the log).
There's pretty much nothing you can do outside of backups - the chunks are gone, overwritten with whatever the seed/generator would create if you recreated the world since any error while loading a chunk causes the game to simply discard it and recreate it from scratch (in 1.7 the game doesn't reset chunks but the items are deleted).
For future reference you want to always make a new profile for each version you use; this can easily be done in the launcher and you can even change the game directory so the worlds are saved in a separate location. Note that versions prior to 1.6, including 1.5.2, have issues using a non-default directory so it is better to make a new one for your 1.8 profile.

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
I do have two profiles, one as "Optifine" (set at 1.8) and then "DukeofHoth" which I've left at 1.5.2....
But, dangit... I guess I went on the world in 1.8 when I made those fireworks the other day. That really sucks :/ But thanks for the help!
