Devourer stacking bug

upon playing a few games using the devourer enchant, i noticed that the stacks didnt show up when i was killing birds, wolves, or the scuttlecrab. they were still stacking however as my enchant went right from 18 stacks to sated. the games counter for the stacks is for some reason not reacting to killing certain monsters, and was not counting when the monster was killed with smite. all of these however, were still adding stacks, it just wasn't showing them in the counter, leaving me to think i had much fewer stacks then i actually did.
