Stuck on Building lot screen and can't close the window
So I got on Sims 4, went to manage worlds and went to place a pretty large and detailed lot from the gallery. (A lot someone else built). When I put it down, it stayed on the building lot screen for twenty minutes. I couldn't do anything, so I tried closing the window. Nothing. Didn't even say the game wasn't responding, nothing happened when I clicked the X. I could minimize it and stuff, but couldn't close it. I tried closing stopping the game through Steam, it said stopping but just never stopped. Then I closed Steam, reopened it and it said the same thing. I turn off the computer, left for five HOURS. Nothing has changed since then.
By the way,
I DO NOT USE ORIGIN, I USE THE GAME THROUGH STEAM, PLEASE DO NOT SUGGEST DOING ANYTHING THROUGH ORIGIN.
