Hello,
The crash you are getting looks like it is to do with the mob attack damage multiplier settings added to the latest version. I think the attribute is being set twice and to 2 different values which looks like a derp on my behalf - sorry about that. I'll see if I can duplicate this issue and fix it.
Cheers,
Me.

jop no poblemo

can you say me when the new v is out

thanks

Bug fix is released and under review on curse so it should be up soon.
@Darkosto should know about this - so flagging him here :)
