Single assets that I place in an empty model seem to load now, but seem to take a very long time to load. I have a sketch up model that only has maybe 15 people in it, and I force closed it after 20 mins or so sitting on the loading screen.
Side note but may be related. Looking at content on the forums, specifically images people have uploaded seems to also take an incredibly long time to load. Its faster tonight than it was today, but still slow.
