I have my visitor access set to Limited Visitor at all of my houses. But visitors are able to use the "Flowers" gem at Seabloom Villa to turn the flowers on and off.
this is a feature,limited visitor just cant touch/change your furniture(light or door)
your house"flower"cant move/delete ,more like a feature(portal or tie rod) limited visitor still can use
if they want fix this,first zos need that flower be furniture..
The flowers in this home are treated the same way as doors in the actual home are; they can't be deactivated from player use without blocking them. Unfortunately it's just a limitation to the system (I believe a similar issue was had in the Craglorn Arena House with the levers.)
The best you can do is block it or create a small gated area around it to stop it from being accessed. I put mine behind the Druidic Sculpture Sphere to make it unable to be interacted with but still visible because I like the look of it.
I will look for a way to block it then. But I wish they would make it so only the owner can interact with it.
The same with player placed doors. I have to leave mine open so visitors can access all my rooms. It would be nice if doors could be toggled on or off separately from lights and other interactive furnishings.
