Major bug
I had rugged helmet on my Togekiss VMAX with lucky energy.
When opponent attacks the effect of rugged helmet puts an energy back in their hand.
In PTCGO I am given the prompt to which energy to put back. In TCG Live, a black screen pops up and you cannot select anything. The only way is to have the timer run down.
When the timer runs down a random energy is put back in their hand AND their energies attached begin to flash. When I press on their energies the prompt returns with the effect of the rugged helmet. After the timer runs down the cycle repeats.
Eventually I discarded all their energies and drew 3 extra cards due to the effect of lucky energy.
The game ended with my opponent conceding.
In the integrity of the game this is unfair and can be used to take advantage of. I hope this can be fixed.
