I started a dedicated server on biomesoplenty world gen and everything worked fine for a while, after it crashed a few days ago it only generates new vanilla biomes. Otherwise the mod still works. The level-type ist still on biomesoplenty.

We can't do anything without logs or a crash report

the problem is that there is no crash happening, i checked the server log and there is no error of any sort

There's nothing that would cause the world to start generating only vanilla biomes unless it somehow got corrupted, which we can't do anything about. The level-type setting only applies to newly generate worlds, and you'd have to use an NBT editor to see what the world type is actually set to in the world now. Also you aren't using the latest version of the mod.
