I've always been haunted by the multiplayer holes that always pop up. There has never been a time in my life that I haven't gone without them. Now, since minecraft became it's on singleplayer lan server, I constantly see these holes and unloaded terrain there. This makes the game unplayable. Are there any solutions?
I have no idea what you're talking about.

Just break / place blocks around that area, it should fix it.
