I am not sure what happened, but I know I made a mistake and took the numbers displayed on the weapon (x/xx) as the number of rounds loded compared to the max for the weapon. I realize now it's not, it's compared to the amount available.
I found this a bit non-intuitive, maybe this could be a suggestion for updating the GUI. If possible show all three numbers, or if that gets too cluttered, I'd think the numbers displayed on the weapon should show its own content/max, and then you could simply open the Inventory to see the available rounds.
Speaking of which, I find the common pool for the team of ammo, grenades and medikits pretty convenient for gameplay, but for increased "ralism feeling" I'd like to have those individually equipped on each character.
I'm not sure about the 0 AP when entering combat mode manually.
Maybe it was because I was trying it on the trade station, where thre are no enemeies?
Since then, I have entered combat mode in missons when it was auto-triggered, and it seems to function normally. I have also been able to shift-click the reload button between engagements to reload for entire team, and it seems to work normally.
By the way I love the game as it is already!
