Minecraft Forums

My friend and I have been working on a LAN world for a couple of months but recently there were a few corrupted chunks that I managed to fix with MCEdit. After the chunks were fixed, the world played smoothly for a few days but now it won't even open.

When i try to open the world, the "loading world" and "building terrain" appears on the screen but then it just reverts back to the Main Menu. This keeps happening without fail until i get the "sending packet" error:

"Minecraft has stopped running because it encountered a problem; Sending packet"

I have been trying so hard to get this world back. We've put so much time into it. Any help would be appreciated. Thanks.

Here is the full error report:
