OH working throughout the game.

...

if red attacks blue during Overlord Hour (OH), nothing changes; it's as if it were a real game. If blue attacks red, it's as if blue has become red (which is what we want to avoid).

As I suggested, we could:
- interrupt OH for a couple of days; this would allow players to save time when continuing the game;
- add a button for red to enable OH;
- implement turnbacks as I described in the thread;

During OH, both players see each other as stationary. When red attacks, the battle starts normally, and blue's turn is rolled back to the moment before the battle; blue will then move (nothing changes in essence). For red, when blue attacks, the same thing happens: the turn is rolled back to the moment before the battle, and then red moves. In this case, the problem arises of visiting objects simultaneously.
