game locked up during Gardevoir ex ability

Paradox91

Used Gardevoir ex's ability twice to attach two Psychic to the active, then the game got stuck where I couldn't attach energy, or stop using the ability. The only option I could select is to attack with Gardevoir. I wasn't timing out even though I sat there a while. Once I selected Gardevoir's attack, Gardevoir went overtop of the gardevoir ex and then nothing else happened and I couldn't do anything except continue cycling the view options of the ability as if I was still using the ability.

I took some screenshots, but it won't let me upload them.
