I've got the festival issue too. I worked for the better part of 3 days figuring out it wasn't any of my mods. Hopefully there will be a patch soon.
Can anyone share a save file of where this is occurring? You can DM me the link to your save, thanks for the help!

Is anyone still getting this LE ?
It looks like this has been fixed.
I don't work or have any association with EA. I give advice to the best of my knowledge and cannot be held responsible for any damage done to your computer/game.
Please only contact me via PM when asked to do so.
