I'm new to the forums, but I have been playing Skyrim PC for almost a year. I recently encountered this bug. I decided to make a visit to Blackreach, and explored for a while. I accessed it through the Great Lift at Alftand. About 5 minutes after I arrived in Blackreach, the loading screen appeared and I was teleported back to the bottom of the lift. I thought "huh that's weird" and kept playing. About 2 or 3 minutes later it happened again. This happened a few more times before I said, "screw it, i'm getting out of here." I used the Great Lift at Alftand again to leave. I fast traveled to Riften after that. About 10 minutes later, the loading screen randomly appeared and I was teleported back to the top of the lift at Alftand. This has been happening every 5-10 minutes or so ever since. Has anyone else ever experienced this problem? Unfortunately I don't have an autosave from before I entered Blackreach the first time, so I can't fix it that way. I also use a large number of mods, so I am trying to figure out if there is a conflict, but that will take forever, so I thought I'd check to see if anyone else had this problem, perhaps unrelated to mods. I'm using Skyrim 188.8.131.52.7 and SKSE. I also have Dawnguard and Hearthfire extensions. Thanks for your help.
