@jupiter_rowland Almost everytime I buy a house in Second Life, my first step is to go to a sanbox, hunt for all of the prims in the linkset that are at the minimim size of .01 and make them .02 or .03, then shrink the entire house down to be like, 75% of its original size.
Sometimes more.
The annoying part is that sometimes the window and door scripts are bad, and shrinking the build breaks them so I then get to go and replace all the scripts too.
