[CL] [LS] White Screen/Endless Loading when loading world with penthouses

After the latest patch both San Myshuno and Ciudad Enamorada don't load when i try and visit those worlds in manage worlds. The game doesn't crash but it leaves me on a blank screen. I can still access the options menu and quit the game. I've checked and its just those two worlds, all other worlds, including vacation worlds, load fine. Removed all my mods and checked again and they still don't load. I'm speculating that it's because they are the only 2 worlds with penthouse lots?
