Linkset Nuked by 'radar"?!?

I created a flying house-boat today just to mess around with non-physical movement of largish things, and was cruising sim-to-sim at around 400m. I was only half paying attention, looking at my laptop (and running SL on the desktop), when I notice a chat message, something like 'radar - attaching icon to Plastic Spoonhammer'. I look around a bit, and see a house - cool! Then all of a sudden, my house-boat is unlinked and half the prims are just gone. Not cool! I'm still sitting in the chair and its script is still running, but the chair's all that's still attached to me. I had made some tweaks to the copy of the script in the chair, so I tried to edit it to get its contents...and couldn't edit it. So I head to ground level, hop off the chair, and same deal. No edit. I was able to take the object, re-rez it, and get the script back, but I'm awfully confused.

I thought you couldn't unlink an object that was being sat on? I just tried yesterday in fact. What gives? And what's this 'radar' thing attaching icons to me for?! =) Can anybody shed some light?

Well, I've had similar things happen a few times now sans radar, and I have a theory - is it possible that a group of prims which are 'close enough' (based on the formula which I've seen reference to here in the forum) can suddenly, upon rotation, no longer be close enough, causing the object to suddenly unlink?

Yes! A related thread is here.

The "attaching icon for X" means there's a sensor around that displays your position on a "radar" prim thing, it's very common and completely harmless.

Seems to me your object is too big to cross sim borders at an angle, when not aligned on East/WEst or North/South, it's over the link limit and thus unlinks spontaneously

Yes it is annoying... I wish SL would calculate the link limits on a rotation-independant basis...

And size-independant. It's really annoying to be unable to add objects to a small link-set because linking distance depends on size, type of root prim, angle, time of day, color of my hair, and whether my ponytail's snugged too tight.

What the hell ARE the rules, anyway? What's wrong with "all prim centers within 20m of root" or something like that?

My guess is you could link a few small prims and up-size the lot to excede the intended limit.

Yes, of course you can. That's how I made my giant clock. You can make things as big as a sim, pretty much... if that's the intent of LL they blew it both ways: they didn't fix the problem, and they set us all up the delink.

Should just have the drag handles stop moving when the object as a whole exceeds the limit. MUCH smarter.
