Mind flayer didn't return control of stolen creature [Investigating]

Janen

My creature was stolen by opponent's mind flayer, which says:

"When this creature dies or is exiled from the battlefield: Return all creatures you control but don't own to your opponent's control."

I took control of it using Angrath's second ability and when it died at the end of turn, my original creature wasn't returned.

Also concerning Mind Flayer I have another bug to report:

I controlled a Mind Flayer and gained control over an opponents creature. With that same Mind Flayer on the battlefield, I exiled another (!) Mind Flayer from my hand. The creature I gained control over was then switched back to my opponent. My own Mind Flayer stayed on the battlefield.

This should not happen.

Edit: The bug is even bigger: No matter how you gain control over an opponents creature, as soon as you exile a Mind Flayer card from your hand, all enemy creatures are returned to the opponent!

This is still happening please fix. When I exile Mind Flayer using Kaya the Inexorable's second ability opponent keeps control of my creature.
