Open JABBA dupe bug (possibly because of moss?)

Summary of the problem JABBA dupe bug

Pack Version 2.6.0

What is the bug? I accidentally put a tinkers pick in a barrel, it displayed a stack of 64 of the same pick (damage and all) and whenever I take one the number doesn't go down. As far as I know all the picks are functional. There was a biomes o' plenty moss on the barrel face? I'm not sure if that's relevant but punched the moss away before the pick went in.

Mod & Version JABBA 1.2.2
Tinker's Construct 1.8.8
Biome's O' Plenty 2.1.0

Is it repeatable? No idea but theoretically JABBA barrel with moss on any side dupes?

Known Fix

Ok I think there's definitely something with the biomes o'plenty mod. The moss covered the barrel face again and turned the number on top into 111
