Last card in hand stash turns invisible and starts vibrating#2715

• Start with two cards in hand and stash both of them.
• Deal one card from the hand stash to the hand.
  • Bug 1: The remaining card is correctly marked as the stash but incorrectly has use_hands = true so it starts oscillating between the two positions.
• After a delay, draw the hand stash to the hand (without a delay no bug occurs).
  • Bug 2: The last card turns invisible and starts vibrating rapidly. It is considered in the hand and shows up in the H hand preview. The card can no longer be interacted with except by drag-selecting it.

To be clear, was the fix for this just removing getHandStash() to make accessing the hand stash directly impossible? Are there plans to restore that functionality later, or should I maybe make a new feature request? Without it, the hand stash seems a bit limited, and I think there should at least be a way to check if a player currently has a stash without manually tracking that information.
