You couldn't possibly make it so that you could "show contents" on all you houses from the server-menu in-game? I mean when you press "Y" to check 'Market', 'My gang' etc etc.
Might be too much to ask, but that would remove this side-effect affecting the scotch-runners, aswell as removing the unnessecary memory-pressure put on the server.
Just a suggestion, everyone would be happy
