While loading a game recently saved seems work well not is the same when loading more former save games: it hangs showing the name of the map, but still responding to Ctrl-Alt-Del.
Also, if you play a lot of turns after saving load causes the city shapes gone, and also the buildings.
There still is a lot of known bugs, but I consider to be able to save and load games a priority in order to test better.
Alt+Tab follow hanging the game, and it is other issue of importance for to test.
In other hand I have noticed a good work for a week. By example now is possible to check the health of your sovereign while him is recovering in a city, or a improved building list, and, indeed, more estabilty.
Keep on this way SD!!
