Suggestion:
When it happens, and it happens, that no-one is covering you, the bot should take the turn, no matter what (in last 30 seconds of a turn in a sequential game). There are some players deliberately missing the turns for deffered troops, this could stop their tactics. I know this changes gameplay a bit, so there should be an option to allow bots to play for you or not.
If a bot plays, the game should still mark the turn as missed turn, but at least you did some damage to the opponents.
