Quickly attempting to replace multiple creatures in succession can cause the last creature to become unresponsive
Replacing a Creature and quickly attempting to replace another Creature while the first Creature's animation is resolving causes the last Creature interacted with to become unresponsive.
Workaround: play another card, or let the replacement animation finish before playing another card.
Steps to reproduce:
1. In a game, cast 5 creatures.
2. Replace a creature.
3. Quickly drag another creature from your hand while the replacement animation is still playing.
Actual Results: The last creature becomes unresponsive and hovers on screen.
Expected Results: The last creature you attempted to play is returned to your hand.
