Agnes Bernauer - card placement issue

[Ms Puzzler]

When playing Agnes Bernauer, the Foundation is set to Ace. However, I cannot place a King on a Tableau empty spot. Please confirm if this is a bug.

Thanks!

The foundation does not always start with an Ace, but can be any rank depending on the first card dealt.

I've checked when it is an Ace and you can move Kings to the spaces, so I think all is working fine.

I believe the issue is that often the base card will change to an ace during play when a different card is shown at play start. It is true that if an ace is shown at the beginning, a king can be placed for play, but if the ace is changed during play, only the original card will be "remembered".

I have had the same problem as long as I've had 3D Solitaire, and it still happens after the recent update. It is definitely a bug.
