And another one: the new Dread Knight seems to be stacking his buff on his followers rather than refreshing it. This group of Zombie Humans has +12 Strength: +6 from the Plains and +6, apparently, from the Dread Knight buff:
The buff list shows the correct value, though. The duration seems to be stacking as well, unless it’s a 12h refresh but a 24h buff:
I don’t have any real-time games with Dread Knights where I can check out the ongoing behavior (and this one is about to die in my SP game). My guess is that if this is indeed a 24h buff, the two castings are just not recognizing that they’re the same effect, and stacking when they shouldn’t be.
