High fey market stealing creatures while owner has no creature on board. [Can't reproduce]

I just experienced a very strange behaviour from Oko planeswalker today.

Oko kept stealing turn after turn my first creature while he had no creature on board (as i was killing the stolen one turn After turn).

Even when I and oko had the same creature on board, he stole my creature and reinforced his copy with mine instead of exchanging.

This issue is now under investigation.

Thank you for the feedback,
Marcela.
