Hello, I have a bug with my config settings being reset. For me, it mainly affects the biome lists for coral, algae and reeds. When I change the biome settings ingame, the settings work fine, but afterwards randomly they get reset to their defaults.
When I manually put the biome id's in the config file, the mod ignores the config and the settings don't reflect what I have in the config file. I'm running version 2.1.5 for MC 1.11.2.
