This is especially relevant for games with a large number of players: Restoring simultaneous turns. I think it's obvious, but I'll give an example: Yesterday, we played with five people. I captured a mine, and the turns were interrupted, but after that, there were no fights or other skirmishes. Several turns passed. You see, right? Three simultaneous turns or FIFTEEN sequential turns! I know you can reload, but it would be better if it could be done in two or three clicks.
