Problem
Objects in worlds start to clutter the world. These are items such as bikes, collectibles, plants, food and drinks. They can't be deleted as they are outside of a lot and even spawn on top ...
Ideas
Sulani is completely full of those boat canoe things for me, I didn’t notice for ages as I was playing in a residential rental then switched to a museum and all the trash that spawns to be cleaned up and all the boats that npcs use have completely filled sulani it’s a mess
The uninstalling packs might not work as the game seems to ignore the openstreetdata if you do that (aka not remove). I'm still trying to find out if there's a way to get rid of stuff this way for console players.
For everyone else I recommend mods to either delete the stuff (TOOL, MCCC, DestroyObjects Cheat, ..) or use S4Studio to clean stuff up.
