We have a homestead sim with a few builds on it. We have plenty of prims to spare, roughly a thousand. But twice now we had to rebuild. We would log back in one day to find most if not everything was returned. This is hurting traffic and moral for the entire sim. I know it's not just us since I asked around and others have had this issue as well. Bellow is what we would log into with the name of the sim removed. Second Life: Your object 'Victorian Chair' has been returned to your inventory Lost and Found folder by -SIM NAME- from parcel '[]' at LAND121, 123 because the parcel is full. Does anyone know why this is happening? I want to think its because someone is rezing a high prim object or something that spawns multiple objects, but the sim should be removing those that are not under the group tittle. We really don't want to make it so only people in the group can rez since many of our activities require others to be able to do so. One friend suggested its a high land impact mesh that someone is rezzing out that forces the sim to compensate and remove other prims first. Again, doesn't sound right (or fair) to me. The sim operates sim edge to sim edge, there are no parcels.
