Console Spam from MCMMO Error included

[Bigpak]

Alright so recently we have been getting this error, http://pastebin.com/SUSfAVag

I've tried updating to several versions of mcmmo, no luck. I cannot figure out what is causing this and would appreciate some help. To resolve this error I have been deleting the server.log once a day so it doesn't kill the filesize and hard drive

On unleashed 1.1.7 (1.5.2)

Could be that mcmmo doesn't know what to do with let's say damage from a mob that is from a mod, as mcmmo to my understanding is a plugin meant for bukkit not ftb.

Also as for your logs I suggest keeping them and swap them out every day then compress the old logs with something like a .tar.gzip that would really get the size down and still let you have all the info.
