Low FPS on some areas
This bug happened from nowhere. I was playing before there and it was fine. But now when i teleport there the game starts lagging so bad that i have to close it with task manager. Also it spams the console like this: https://pastebin.com/47GPPqQt. Logs have nothing in them related to this bug. I can upload the world if needed. (Sorry for mistakes)
Also i am using 1.7.10
my best bet is that the image for that area is corrupt.
if you know the region that the image is in you could try and delete/move them out and see if it still gives a problem
Can an out of memory crash corrupt it?
crashes can always corrupt things. depending on what the game is doing when the crash happens
There was a lot of stuff happening.. Usually crashing because of the 1000 entities (dropped blocks) from mining 11x11 holes
But how do you find the region?
if you know the block coordinates or chunk coordinates (both visible on the F3 screen) of the area you can use: Convert tool
Deleting regions didnt help
