Recently after the 1.3.1 patch my single player world has been lagging. The lag includes, sound delay(as in walking) ender pearl delay, updating delay, basically there is a delay on everything. This only happens on this one specific world, the rest of my worlds are perfectly fine and don't lag at all. I have no clue what's happening with this one specific world.
Whenever I throw an ender pearl it doesn't teleport me or it teleports me five minutes later. If I mine something, for example stone, the cobble pop up animation does appear, or it appears 5 minutes later. My world also takes a couple minutes to load in chunks. There is also inconsistent frames so I can barely play sometimes. Any idea on what is happening?
