Whenever I want to open my city, my game crashes. I always get the error: The game crashed while exception in server tick loop
Error: java.lang.IllegalArgumentException: ChunkNibbleArrays should be 2048 bytes not: 0
(I'm using version 1.12.2 with WorldEdit and OptiFine (Forge Modloader)). What does the error message mean and how can I fix the error?
That probably indicates a defective chunk (believe / I hope):
Hm, I had previously opened the world briefly with 1.13.2, without mods. Maybe it's because?
Yes that's it, with 1.13 was a new world formatting introduced, this one can't undo as far as I know.
The world is now probably only for the 1.13
Hm, luckily I have a backup.
So. Have recorded the backup, it is fortunately 1.12. Thus, the topic has probably done xD
Minecraft crash… What does the error message mean?
If you do not understand an error message you should still read it first and try to understand. 90% of all error messages can be explained by simply identifying themselves. Then you should use the error message Aunt Google.
