Spawn of N'zoth (mercenary mode)

Hello, machine translation (‘jerk:joy: No offense intended, just turns out fun sometimes). But more seriously, this is a known issue:

That’s how it has always worked, and it seems to make sense: once you ‘take control’ of a minion, which is what the ability does, the creature no longer ‘controls itself’, losing its queued ability. I don’t see why we should consider this a bug — seems like a design choice, arguably.
