Timed out/Roped just when I was casting Charming Prince. I had manually saced one of my treasures for white mana and also manually tapped Steam Vents for blue(or red, pretty sure it was blue). Cast the card just when the time ran out and it sticked on the screen even though the turn had changed to the opponent. He played cards and they looked like they stacked on top of Charming Prince, but they got resolved, while he stayed. He attacked normally and on my turn I could click on Charming Prince at the same location, but as is if he was in my hand and I could cast him normally, but I had to pay again, the mana from last turn, was gone. I have uploaded a picture of how it looked like during his turn.
Good hunt! :)
