Still no patch from Steam yet, and I had a strange occurrence after creating a copy of my install and trying to add the patch manually. The first game I started, I clicked a few different nations and start dates, before beginning a 1399 grand campaign as Muscovy. In the beginning of that game, I started with 5 regiments and was at peace with the Golden Horde. After goofing around and getting into a major war with Novgorod and having Smolensk emerge with my westernmost province (which I wasn't able to take back from rebels because of the 15+ regiments of Novgorod mercenaries), I decided to start over. When starting the second time, I only clicked on the 1399 start date, and selected Muscovy - no in between clicking on other nations or years - when the game began, I had 10 regiments and was at war with the Golden Horde (just like in 5.0, but I had all the new map-view options, so I didn't accidentally run my Steam install).
