Issue
When starting my server Forge Mod Loader displays the following message.

[main/WARN] [FML]: The coremod lumien.bloodmoon.asm.LoadingPlugin does not have a MCVersion annotation, it may cause issues with this version of Minecraft

The mod appears to work fine and does not crash, however I do not know what affect this may have.

Steps to Reproduce

1. Add Bloodmoon jar to mods folder
2. Start server
