Just want a sanity check.
For the ancillary:
Preacher of Decay (Common) Recruit Rank: +2 for Plaguebearers of Nurgle and Exalted Plaguebearers of Nurgle units (factionwide)
I've tried putting it multiple ]combination of lords and heroes, but I only seem to recruit Plaguebearers at rank 1 - the same as all my other units. Am I missing something or is this item bugged?
