Hi, I'm in the middle of a build on my land and today have been getting this message everytime i try to link the last parts of my build. The build is about 200 prims in total and I have about 1800 prims available still on my sim. I also get this message when trying to rezz some objects and not others, all well under 1800 prims. I've never had this issue before on my land, anyone know what could be causing it? It's not overly scripted either, just a car shell with light scripts, the main car script is in the chassis base which I do not have rezzed at the moment.
