Quakes and missing prims

A friend of mine had close to 300 prims leftover on her land one minute and 177 the next. Over 100 prims, gone. It all happened very fast. She hadn't added anything to the land neither did anyone on the lands group.
Another strange thing that happened at the same time was she experienced a minor earthquake. Sounds strange but she said the whole place shook. Plus a lot of the items on the patio and inside the house were all over the place, up in the air and all strewn about.

How is this possible?

We proceeded to check the entire land including the air and found nothing that wasn't there before except a few skyboxes of other people nearby which hadn't been there prior to this. There's no way of measuring to tell if any of these boxes were on her land.

Is it possible for someone to of laid something on her land whether they're aware or not?

How can you check to see if this is happening?

We also checked in the place where you return items which belong to others but there were none to send back.

She contacted AC the lands management team but the one person who finally responded after several calls and a long wait wasn't any help whatsoever. So she'll have to try to try to fix this problem later today then.

Any help will be appreciated.
Thank You

She needs to stop playing SL under the influence of LSD.

Check the table and monitor to make sure it is all sitting firmly and not wobbling. Also, find out if she has a pet or child that could have bumped the desk.

You guys haven't seen spontaneous terraforming yet? Wow. I've seen it twice, I just assumed that meant a lot more people have seen it. One time I saw it, it happened in a public LL-provided sandbox, so I know it wasn't just the "allow anyone to edit terrain" setting.

Got no clue about missing prims, but stuff goes missing in SL all of the time, so that's not really a surprise

Sounds to me like an attack with explosives in an area where the no-push protecions are not in effect, or possibly an attack with physical objects, that caused other Physical objects to move. Most stuff in SL is NOT physical, but I have seen a set of wind chimes blown off their post by an idiot with explosives, before no-push was available.

As for the prim drop, select 'about land', and the Objects tab, and have it list the owners of the objects on your parcel. A skybox probably got moved over you. If so, you'll see an unknown person's prims listed.

One way to check if something is actually over your parcel is to set marker posts at the corners and edges of the parcel, and then ride a prim up, 20 M or so at a time, moving the posts up with you. I do this all the time when building above a parcel, to ensure I don't encroach on someone else's land.

Earthquakes and other spontaneous effects do not exist in SL. Everything has a cause.

I lose objects all the time. Once I noticed the ground was shaking.
No clue why but eventually my objects return. Sometimes I literally cannot grab them or they poof somewhere. Sock monster eats them or I find them in lost and found eventually.

I was Terraforming on a sim for a friend, when a Griefer Managed to Highlight the Entire sim, and Raise it's elevation by 100 meters.
It's Probable that your friend has had someone deposit over 100 prims, (Maybe Bullets or something like that) Then Attempt to Alter her landscape That would be the Earthquake). Tell her to Check around the Land Using a scanner for objects that do not belong to her, and she Should check at 100 meter intervals in the air above her land up to a hight of 800 meters. The Prims Could be Invisible/Phantomed or Very tiny. They could also be below Ground. Some persons also deposite Invisible scripted devices that would Inform them the second land is made available for sale, so she should. Search for scripted items.

Things like this don't happen on their own, But the Cause is Probably Innocent. In the long run though,it's best to be cautious until she knows for sure.

Angel.

Well, I agree that everything has a cause, just like in real life. But that doesn't mean that it's not spontaneous from the point of view of the observer, just that the cause is not known.

And the funny thing is, one of the times I've seen spontaneous terraforming, even the Lindens did not seem to know why it happened. I was in a group of folks that saw it, so I have a pretty high level of confidence that it was not an isolated client rendering issue.

I've also seen my entire parcel of land drop about 0.2 meters (or everything above it rise by the same amount, I can't begin to guess which). I had gotten logged off because of a grid-wide attack, and when I relogged, everything that was left on my land (lost a lot of stuff that day) was higher than the ground by a noticeable amount.
