Collectible Card Game Headquarters

Describe the Bug:
Creature controlled by Preacher returns to owner when you cast any spell

Which card did behave improperly?
Preacher

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev version 250c78bd updated 11-5-19

Confirmed also affects Old Man of the Sea and I guess others with same rules text.
Edit: The problem seems to affect only with cards with clause "as long as x remains tapped".

Confirmed for Vedalken Shackles, Merieke Ri Berit, Rubinia Soulsinger, Helm of Possession, and Seasinger as well. In the case of Merieke Ri Berit, the stolen creature is properly destroyed rather than returned to its owner.
Callous Oppressor has been coded in dev, but not enabled in my version (778ccb5)

Fixed all in commit 73e7e016.
