Bugfixes:
- Fixed an occasion where escorting soldiers would never return to the troop
- Fixed separated soldiers not regenerating physical exertion (a hidden value that causes the 'Out of breath' attribute and increasing exhaustion per turn)
- Fixed that soldiers that are already retreated still can get wounded by artillery
Balancing:
- Influence of the number of active soldiers in melee increased
- Influence of morale in melee combat slightly decreased
