Skyrim - glitching out of Solitude and riding to Whiterun

like before in Whiterun, i left the city of Solitude without using the loading gate. i glitched through the wall and floor to leave the city. and now its clear: not only villages like Morthal (which have no loading entrance), but even other cities don't get loaded. only the one you left stays loaded. interesting, but also disappointing, since theres nothing to see and do in an empty Skyrim other than see the ground under city houses. oh and btw i use a double jump height mod, so this route propably wont work without such a mod. but theres multiple ways to get around the invisible walls surrounding Solitude.
