'System Error' when placing lot

I just noticed this today when I went to download a build off the Gallery. When I download the lot, it clears out the old lot as normal to make room for the new lot, but then it says there's a system error, and it won't finish downloading. I tried this across numerous saves, in different seasons, I've even bulldozed the lot ahead of time, and it all ends up the same: there's a system error, and the lot won't download. 

I don't use mods/cc, and I even repaired the game. Nothing seems to have worked, and I don't know what could have caused it. Any help would be appreciated!
