For some reason, after updating my game to 1.18, some of my existing Nether biomes have changed too Overworld biomes (in the code) for some reason, and so I get Overworld hostile mobs spawning in these areas, which makes traversing the Nether ever harder.
Note: I am using mods, and I did report the issue to the relevant creators first, and they said that they don't officially support upgrading worlds and the issues that it brings, and that I should take up the issue with the official MC bug tracker. Even if a change is made to prevent Overworld biomes from being able to generate (in the code) in the Nether, any help would be appreciated ![]()
World Type: Custom
Seed: Occuring in at least 2 of my worlds; no specific seeds.
I had Bonus Chests turned on.
UPDATE: This issue can be reproduced in vanilla; I have loaded this on the same world on 1.18.2 in vanilla, and this issue occurs in the same locations. I have posted new screenshots below:
