Collectible Card Game Headquarters

Describe the Bug:
Preacher untaps but creature still controlled. In this example, the AI has 2 preachers and somehow manages to control 4 of my creatures: Paradise Druid x 2, Tiana, Ship's Caretaker and Uril, the Mistwalker.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
most recent version: Happy Holidays 2021 / gauntlet

What exactly should be the correct behavior/interaction?
If Preacher untaps, the controlled creature is returned.


Are any other cards possibly affected by this bug?
-

This is confirmed in dev, too. The bug happens only when AI has Preacher. The controlled by Preacher creatures return for a second to their previous controller when Preacher becomes untapped and then return to AI without the legacy that they have been stolen by Preacher.

EDIT: after some more testing the bug happens with human, too. It happens only if you have two or more creatures with such an ability and select to untap more than 1 of them.

This is a duplicate of this: viewtopic.php?f=86&t=30344#p247740 but will keep this and archive the other. as this has more info. I was sure that we have met this again, this time my memory didn't play tricks on me.
