While playing against an opponent that uses Millstone, it was the opponent's turn and while the game slowly made him mill one card at a time for +30 permanents that untappd, it started ticking down my time out fuse despite having nothing to do and nothing do resolve or interrupt.

Additionally, if I turn on auto-passing, I should not have to click resolve on every move and every step of the opponent's turn, that defeats the purpose and is really annoying.
