The full story.

So, opponent had two cards in hand, an island and a plains . I used the ability, x=2, naming Plains. However, the naming window didn't go away, so I already was freaking out. I didn't see the opponent's hand, but the game chat said that the hand had an island and plains in it and the plains was discarded.
Then, the game started again. The timers were reset, but the game chat wasn't. Not only that, but when I, in this new game, could not see the lands I play, but my opponent could.
