This may have been reported before, for all I know, but I have no idea if it was.
My land is in a sim corner. Beyond that corner, in the diagonally adjacent sim, was an interesting structure that I decided to investigate. I walked right up to the property, and suddenly found myself completely disoriented and puzzled as to my whereabouts. I got the "You've been kicked out of the property" message.
What happened was, as I was not in the same sim, I didn't see a red "police tape" as I approached it. Possibly because there was no red tape, I was allowed into the property instead of bouncing against the wall. Then, this being in the corner, when the property kicked me out it moved me to beyond 255,255, which rolled over to 0,0 and I found myself in the opposite corner of the new sim, quite some distance away.
Translated, property kicks don't push you out of the sim.
