Today while playing a QM as Arthas I encountered a bug in which the ghouls summoned by Army of the Dead would become unresponsive after being cc’d. Multiple times I noticed my ghouls no longer following me and just standing still right where they had been cc’d. First was by Mei’s Blizzard stun and then again by Falstad’s gust. Minions could be sacrificed for health still but would not attack even minions that were in range.
Thanks for the report, I’ll take a look into this now!
If you would like me to share the recording of the game please let me know. I rewatched the game myself to see if I was crazy but it in fact looks like a bug. I know I won’t be picking Army any time soon after checking that out.
