Hello, I started building the Willis Tower in MC in December. It was fine than and I took a break. I reloaded it yesterday (It is on a Hamachi server) and no blocks would load. All I can see is paintings and the bows of skeletons. I moved all the world info into my saves so it was singleplayer and the problem persisted. I thought maybe it is the level so to test it I made a new one and had the same problem. I then deleted .Minecraft and just kept the save with the tower. Once I re downloaded, I opened it up and sure enough the problem was still there. I also copy and pasted the tower via McEdit to another level earlier to see if it was the specific level. I even upgraded my graphics drivers to see if that would help. As you'd expect, it didn't work. If ANYONE can help me whatsoever it would be greatly appreciated, thank you.
No Blocks Loading, Tried A Lot of Things.
