Gallery constantly inaccessible, llamas all over the map, lots keep disappearing
So my game's kind of in a crisis. I keep traveling to a lot, only to find that the lot is completely empty for some reason once the sim arrives. That wouldn't be the worst problem in the world EXCEPT THAT I can't even download a lot from the gallery to play with because each time I try to access it there's a new problem. Red X's start appearing over every download and each one says that it 'could not be located'. Sometimes, the gallery asks me if I want to connect and then loads infinitely (never times out).
I've tried disabling firewalls, toggling online in the origin client, clearing caches and repairing my game multiple times but nothing has helped.
ALSO there are llamas all over all of my maps. It's getting to the point where I can't see any of my lots and have to hope my cursor scrolls over the lot location in just the right way to play the game at all.
Now, I know what you're going to say-it's because I have a ton of mods and cc and also my laptop has diminishing storage space. HOWEVER, I have been able to replicate these glitches with no mods or cc installed and have deleted many files from my computer just to make the game work and the problems persist. I'm pretty much at a loss as to what should be done about these issues that are making the game unplayable for me.
Many lots also throw errors like the type attached for me when i just try to visit them. Any help?
