Hey there, just putting in a bug report per the suggestion of the customer service peeps.
A few days back, I went out of my way to get the achievement for killing an opponent with Mankrik, Consumed by Hatred. However, I didn’t get any progress for the achievement, while other achievements got completed just fine.
Worth noting, while the opponent was destroyed using Mankrik, Consumed by Hatred, they were killed from a regular attack, not the attack triggered by his summoning.
For the sake of providing as much info as I can, I’ll also mention that my minions were affected by Wave of Apathy.
I hope this is enough info for you to go off, but please let me know if there’s anything specific I should be telling you.
