Thanks for the tip on #1. I'll try it but it'll take a few turns, my only general with that ability is currently leading an army. As for #3 I found it by accident, it's the button with the 'skip to the next track' symbol.
I'll keep testing Patriot for now. And one more question has come up: it looks like German (in fact, Central Powers, because I have this issue with Austrian and Hungarian units too) reserve infantry (in the alternate history scenario) can't be trained up. Has anyone modded them to be trainable ?
