1.Added minimum distance between settlements of different factions. (default: 7 tiles)
-------------------------------------------------------------------------------------------------------
Update March 10:
1.Changed the conversion time in the mod settings from in-game days to minutes, as in-game days are not accurate.
The default interval is 16.7 minutes per expansion; at 3x speed, it becomes 5.56 minutes per faction colony expansion.
2.Increased the default faction outpost limit to 99999.
3.Added a one-click button to restore default settings.
4.Added more detailed logging options.
5.Added notifications for faction relations when new settlements are founded.
6.Added optional notifications for new settlements from neutral, hostile, or allied factions

Update April 12:
1.Fixed an issue where selecting one type of letter would result in sending a different type.
2.Increased the maximum expansion time to 240,000 game ticks.
3.Exiting the game no longer resets the tick counter; the tick value is now saved with the game. This prevents factions from failing to expand due to the player exiting mid-process when expansion takes a long time.
