So, I'm playing a domination game, and the game is drawing to a close. In fact, it has me winning the game in 6 hours. The problem is, I know that not to be the case, as my enemy has a nav that will be re-routing and delaying the end. So I'm trying to schedule a nav re-route that technically occurs post the theoretical end-of-game. This re-route shows up as red in the time machine, and displays as a dashed red line leading to nowhere. And skipping forward in time, the nav does not re-route.
I'd like to think that it's going to happen, but it occurs while I'll likely be sleeping, and is rather critical, as future moves I'd scheduled previously rely on this.

Reroute now. BTW the sentries have such large ranges

Not sure what you mean...

As for the sentries, mine would have covered the entire map, had the game lasted a few more hours. My enemy's was similar. Made for interesting tactics, with both of us having 3 generals.
