I played with a mod pack in which there was a gregtech and after 190 minecraft days I try to enter the world and the game crashes.
It was java.lang.NullPointerException: Ticking memory connection.
Every time I tried to enter the world, the game crashes. In other worlds everything was ok. I found a solution to use mcedit. There is a “repair regions” button. It helped me and I was able to enter the world.
