Numerous game actions (i.e. death of a creature, selection on a modal spell, creation of tokens etc) lead to game freezing and no possible action on any button/object, without warning (so you realize it when it's already stalled for 10-20 secs). Need to restart client each time, leading to additional waiting time (30 - 120 secs) and game losses. Game is largely unplayable due to this issue, which happens multiple times in a single game. Restoring files etc doesn't work.
