i installed the new patch today, 2/24/15. after installing, several issues came up.
first, i could not continue any previously saved games. when i hit continue all that came up on the screen was the map. fields, farms, orchards, roads, etc. no data. no units. no anything else.
second, after trying two times to continue a game i initiated a new game. after playing the new game for about 5 minutes the entire screen went black, then i had to hard restart.
third, after trying a second time to start a new game, i played that game for about 5 minutes and same thing, black screen, no response, hard restart.
this game has so much potential if all the bugs can be worked out. until they are, it's very frustrating and perhaps not worth playing.
