Hello there, it seems my land contain an unknown, invisible physical prim, not detectable, in one spot 10x10 meter, my avatar cant walk in that area, he cant move in this area. l makde a basic cube and try to let my avatar sit on the cube inside the affected spot, SL says: its no room to sit -try another spot. I already test to not using my antivirus and firewall but still same issue. I just drop a ticket to LL. Anyone here who knows what this is??
