This means there is a mod incompatibility with polymer

Might just have to replace server.getOverworld() with server.getWorldData() (Mojang mappings)

@Patbox The worldthreader mod runs each dimension on one thread and tries to prevent other threads from accessing the world in a non thread-safe manner during the world tick, e.g. by hooking into the MinecraftServer methods that access the dimensions, e.g. server.overworld(). Do you think you can inline the getEnabledFeatures() call, which actually doesn't access the world at all? I think this would fix the reported mod compatibility issue, but there might be a lot more.
