I've had the same issue with two skeletons after using The Ritual Stone in a amazing situation. A few of the skells followed me in a fast travel and inside Whiterun and have been sitting at the gate empty since. Everytime i touch them a guard calls me a pickpocket for some weird reason but its no big deal. I also got two "unallowed" redguard guys standing at the gate from the redguard traitor quest that never seem to go away.

Lmao. I did the same thing you did. Grabbed all the coolest looking mods out there and ran them at the same time. In the beginning I just kept crashing every other fast travel, but when I went to unload a few mods to help fix the issue my game started just crashing upon launcher or start. Good thing before I mod anything I always make a backup, just restored it to the previous version of the folder and back working. Next time just do one at a time and see if you can pinpoint the mod that caused the issues so the developers can fix the bugs.
