There has been a new patch released for Birth of America that fixes 3 minor glitches/bugs.
UI
Regions are now cached with the same (hopefully improved) system as AACW.
New icons for army waypoints (land move, sea move, final destination)
The battle animation (needle moving back and forth) can be disabled or the delay changed in the Options|Display window.
AI
AI will be more prudent when it comes to split artilleries and supplies.
AI will resupply better.
Gameplay
Units will only retreat into a city/fort if the special order "enter destination structure" is activated.
The artillerist trait now gives a bonus in siege (by boosting slightly the artillery value. Siege leaders are still more potent though)
A force with an unactivated leader can't sortie.
Some inconsistancies around city capture have been fixed.
The command penalty can't go above 5% per missing command point. It means than small, uncommanded forces, don't get the -50% penalty now.
Retreating into a city/fort won't prevent you from being attacked again in the same turn.
Attack delay (commiting unit), new game rule from AACW, retrofited as an option in BOA (Options|Gameplay, default is ON):
Units won't necessarly engage the enemy as soon as they are in the same region as him (the posture rule still apply, if both are on defence, neither will engage fight anyway). A delay can occurs, ranging from a single hour to several days. The chance to engage the enemy depends of:
a) if a leader is present or not (strategic rating)
b) if some of your units are already commited.
If a fight is already taking place, the delay is usually from 0 to 3 hours. If the fight has not started, several days is not unusual.
