Faulty Chunk Load

As always, I've got another bug.  This time, whenever I go to load my Main Save, it always fails to load Chunk -28 4 28.  When this happens, it always resets the chunk, resulting in loss of my personal livestock, (namely my sheep), my data, and my house, (or, at least, part of it).  It always seems to be that exact same chunk that fails to load and as a result resets itself.  I don't know if there are any others.  But that one is the most severe, (especially considering my lava moat is right on the other side of that and it caught fire to a good portion of my base.  Plus, my....  OH CRAP!!!!Unable to render embedded object: File (  I think that reset may have aligned with my Ender Portal, although, it's rather weird that the Ender Portal and that portion of my wall are gone, but the Lava Moat isn't, (neither are the Cacti that exist on red sand that sits right at lava level).  It's all very strange.  Hmm, come to think of it, that whole section had my Mob Spawn Egg Collection displayed on it, in item frames, could that have done something?  Anyways, I'm sure you find it, oh, and I'l be including a copy of the current world save for you to look at in the first comment, (even though you should still already have it form the last one).  Rockatoa, Brickticks out) not found.
