Hello, for 4 days now I can't rez objects in my linden home. I Have it set to group, have my tag on and only a few prims are down. I am trying to rez. 1 or 2 prim objects. I can build a object prim but if I take it up I can't put it back down from inventory. I have cleared cashe several times, if I tp out and back some times I can rez a 1 or 2 prims item once but then I can't again. My group members are having the same problem. Also the sim is very laggy, I have taken off all attachments and huds but it doesn't seem to help. I have waited for 3 days because I know you have been trying to get the mesh situation straight and there are problems all over SL. My Linden home is in Coyote Melon (96,196,42). I am having no problems anywhere else in SL. This is the message I get: [ Can't rez object at { 86.5557, 184.187, 38.6059 } because the owner of this land does not allow it. Use the land tool to see land ownership.] I am the owner. Thank you. Tinker
