Bow in Blue does not spawn blue fatties

There’s a bug, where in the mad mage campaign the fatties does not spawn anymore..tested bow in blue only - the shield/orb popping on person, who would spawn the blue mob, but mobs aren’t just there..thank you for looking into it..it has been useful way for people to lvl up and to make the mad mage quest faster

Can confirm. This is particularly odd, because earlier today I was doing a Bow in the Blue run and they spawned just fine. Now they don't.
