Townhouse has infinite loading screen

Could you please provide the following information

• Are you using mods/cc in your game ? Please remove them and test without them if you do. Please pick a thread tag for that.
• Any LastException/LastCrash files in your documents folder. Upload them to either google or oneDrive and post the link here.
• Is it just that house that's not loading or also another ?

Please follow these steps to test  your game on vanilla game with no mods/cc

• Create a backup of your save game
• Move your mods folder to the desktop
• Delete the following files from your user folder.
  •  localthumbcache
  •   Any lastException Files
  •  Any LastCrash files.
• Test your save (you will loose all cc on the save but since you created a backup you can go back to that afterwards) and see if the same error occurs, then report back. Reupload any LEs you get from an unmodded game.
