this has happened a couple times when rooming with people and i still dont know if there is an easy fix. But when someone puts down a texture on something that isnt a prim they rezzed, it gets attached to certain parts of the house's build. whether it be a chunk of the floor or a wall. is there a way to re-rez the house with the old textures and put it back exactly where it was so the house doesnt have to be re-furnished? or some other way of fixing this error if you dont have access to the original texture that used to be there? any help would be appreciated thank you ^^
