Bouncing a creature controlled by Exert Influence

BigMao

In the Events, I took control of my opponent's Oblivion Sower using Exert Influence, and it was bounced on a later turn. I don't remember exactly which card the opponent played that did the bouncing, perhaps it as Harbinger of the Tides, or Crush of Tentacles. Interestingly, Oblivion Sower went into my hand instead of back into my opponent's hand. I don't even own Oblivion Sower so that should probably be filed under bugs.

Happened to me in reverse(opponent got my creature and I bounced it to their hand).

I checked on descriptions.
For all bounce effect i checked, it states "owner's hand".
Based on the meaning of that in paper magic owners means the one that had the card in the deck at the beginning so should be a bug.
Anyways since this is not paper magic it could even be intended(making owner and controller basically synonymous).

Last word to the devs.

It'd be boss if you got to add the card to your collection
