Crash Server SpongeForge (Foamfix)

The issue seems to be this line.

[Server thread/ERROR] [FML]: Unable to parse dependency for mod 'animalium' with dependency string 'after:BiomesOPlenty'. The modId 'BiomesOPlenty' must be all lowercase

Which is a hardcoded error in the mod animalium, you should report it to the mod developer
