Ideas
So I looked at your save and these lights are in the open street data along with tons of plants (I think you can delete them too, they are probably invisible).
Navigate to Streets and then find the OpenStreetsData with the world_Id B2F36125
scroll up to objects and delete everything with the following keywords
- garden (plants)
- invisera (the lanterns, possibly other stuff that's not needed)
- dirt (dirt mounds)
I think it's save to delete them them all but do make a backup. I didn't test if everything is fine with the festival as I would need to play through 2 weeks.
I have two theories how this happened that I need to test out.
- These are all objects that got added to your residential rental but when you changed it back to residential, these got stuck in openstreet. You still can't clean them up but they got added back to where they initially belong.
- It's the festival issue that I have no clue how to trigger.
Will test case 1 (not sure if I have time today though) and if that is not happening, I will move this over to the festival thread.
EDIT: I tested my save where I have never been in the neighborhood before and traveled there (the openstreetdata is only created for those hoods you visited) and this is what I had (no festivals there yet)
Guess it's best to leave those but you can remove everything else
EDIT EDIT: I tested my theories and the first one seems to be correct. I took my residential rental save that had a snowman and angel stuck in the r-rental inventory and made it a regular residential lot. The snow angles and snow pals were in the streets afterwards .. they did despawn after a while though.
Thanks. Unfortunately S4S for Mac is crashing when I try to access the Save Game Data. Might try again after the New Year.
Ok. Well I decided to see if the Windows version of S4S would run in CrossOver. Yes. Very slow, but workable.
