Battlecry creatures don't cause to discover options, bu do it auto at the end of turn

Hi!
*) >>What game mode?
I’m playing a Wild, best mode in this game © ccg_gamer. imho - it not very important in this case. But I’m sorry, because I’m not try to test a least Standard Mode

*) >>Which battlecry minions were involved?
Any card I’m had playing. For example “Stonehill Defender”.
Sorry I can’t remember lots of such cards - I think maybe this info can be loaded from logs).
Also I share some from my recent decklists:

*) >>Did you or your opponent play them? Were they played from hand or brought into the game in another way?
step 1. I played creature with battlecry, eg “Stonehill Defender”
step 2. No any activity with UI has been occurred. But I can to over my hand’s cards
step 3. Random card goes to my hand (I suppose that was 1 option).

*) What other minions were on the board? What spells were played by you and/or your opponent in the prior turn(s)?
Nice questions - But I’m very old to memorize such info =)))
But I will notice it in a future, of course.

*) Screenshots don’t provide nothing to bug fixers, next time (if similar occurs) I will capture video or animated gif.

*) The bug was only 1 evening and never occurs again.

Good Luck for developers!
Sincerely,
Serg Samixon
