V-UNION Bug

So, I am new here, and I dunno if this is where I am supposed to be posting this, but I found a bug, where when I tried to click on my Mewtwo V-UNION to attack with it while it was in the Active Spot, it just did a little bounce and it wouldn't let me see the attacks or retreat or anything. It was fine while on the Bench, and it summoned just fine, but it won't let me attack with it or view it at all, thankfully I was playing against the AI, so I didn't lose anything when I was forced to resign, but now I can't play with V-UNIONs. Please fix this bug, I wanna play with V-UNIONs.
