Cursed items spawning in Ravenwood

I was playing with the haunted house & paranormal investigator in Ravenwood when I realised that next to the big tree with Alice, the haunted house cursed items (dolls, ghost puddles, spooky hands) spawn there too. There is also a large amount of spawns for muddy puddles and trash for some reason. I turned the haunted house off and quit the career but the items still keep on spawning on that place. The items also kept on spawning after I changed my sim's house. 

I don't play with CC or mods.
