The patch for "Immersive Citizens" allows Heimskr to go back to his rebuilt house. It overrides Heimskr's sleep packages with different conditions, so that he doesn't spend the night standing where his bedroll is no longer there [all this in case of a Stormcloak victory, otherwise he'll stay in his cozy cell]. If you do have Immersive Citizens but don't care about Heimskr's well-being, just don't install the patch.
Once you get started, the map system is where you'll begin. The map system is where the cities are managed, armies are created and moved, and the politics of the game take place. This really could have been a good foundation for a game in itself as there are numerous aspects that would keep fans of turn based genre games engaged for some time. Besides the expected elements, other concepts enhance the strategy possibilities. The position armies are in for instance effects how the battle is fought, as ambushes are possible and even the strategic placement of the army should be considered before engaging. In addition, armies can be combined, a city can be put under siege, you'll watch your family grow to become generals or governors and even be killed, and many other options that all create a dynamic experience. You can even let the computer run the battles and give you the outcomes, but I doubt that option is used much.
