Invisible "non-prim" blocking my door

This is weird and I don't know what to do. I used to have a sculptie bolder on my land next to the water. sometime over the past few days it's vanished. The "parts" of the sculptie I've found scattered around my land. I've deleted most of these, however I can't get into the door of my castle. You walk towards the thing and it knocks you sideways. Setting "show invisible objects" doesn't show it. Nor does highlighting a huge area around it. Even going into wireframe can't show it. I deleted the entire front side of the castle to no avail. Any ideas? Go here if you want to have a look.

Feel free to click on the door and try to go in. It *could* be something on my Av but I even tried going in naked...

Also, where would I report such issues if no one here could help? Jira? Support?

I think you can go into the land menu and in one of those tabs view objects owned by others where it will be highlighted and you can access it that way.
Or just simply set auto return and anything not yours will go bye bye.

It says I own them all... Autoreturn is already enabled as well.

Usually restarting a sim fixes ghost prims. File a ticket with Lindens, or call the 800 number maybe...

Looks like a private island so you will need to contact the sim owner and explain the situation and ask for a sim restart

Thanks all. Doing a forum search on "ghost prims" shows me shows that this has been happening quite a lot lately.

I'll ask the island owners for a restart.
