Normal = 3 days
Unfriendly = 2 days
Hostile = 1 day
War = 12 hours?

This would be more doable but still a problem in hostile and wars. A 24 hour period where you can't do ops in Hostile is a lot.

Now if you went this way:

Normal=3 days
Unfriendly= 1 day
Hostile= 12 hours
War=6 hours

You might actually have something you can work around in a war. The current system is a total sham for players that did everything they were asked to do and play by the rules.

The aid thing also must be fixed. If I select a province by accident and send aid, it can't just disappear. Give a warning or something instead of the Access Denied so the aid isn't destroyed.
