Summon Reaper of Revenants + Null's Inclination Trigger minion on kill

I may be wrong but minions specifically reaper triggered via null's summon on bow kill will spawn a revenant but only 1 will behave like a normal minion/reaper the rest; either be 2-3 or 4 extras reapers will not move at all, they will spawn and not move or attack, use skills, etc.

Not sure if is a known interaction in particular that is broken or it is a known bug indeed

I'm using the dark monarch helm with the Reaper of Revenants and it seems like the reapers spend a lot of time standing around not attacking, even with signal prey marking something. Hopefully they can fix this!
