Crashes by exploring outside the already explored map

[TheSwitzVirgin]

The game basically crashes after I explore outside the already explored chunks, I have a 3 year world with this mod and it never crashed because of exploring. I already explored alot, but not thaaaat much so that my PC couldn't handle.

I tried updating the mod, to the newer versions but it didn't help.

I had to get my world on a backup some time ago, I don't know if that is the problem or if it is related to it. From what I think, the save file isn't corrupted.
