Giratina and Cramorant give opponent infinite time

Playing against a lost box deck, my opponent did the following the sequence:

Put Cramorant in active spot.

Put Giratina on bench.

Quick balled a Comfey into play and put it on the bench.

Attached a psychic energy to Giratina on the bench.

Game then crashed and gave the opponent an infinite clock. No response from opponent when I gave the question gesture.

I was forced to concede and as a result go down the ladder 😥.
