Recent bug/potential hack?

On mobile (Android)

Twice now in two days, and end of opponent's attack phase (two totally different decks, both opponent's deck and mine) the game does not progress to opponent's end phase. My timeout rope appears with no options, because it's not my turn, burns my timeouts, waits a bit, activates my timeout rope for a last time, and the game "ends" but doesn't give a victory/loss screen. Options wheel disappears, preventing me from leaving the match. Can still emote/interact with companions, but the only way to exit the match is to force close the game.
