My Sims cannot go up the stairs or into the 2nd floor bathroom

Any Mods or CC: Yes
I have this problem with my sims. My friend made a home for my sims and uploaded it onto the gallery. I downloaded the home and put it in a lot. I have been adding a few house items from the game (non-cc or mod related) into the home. Everything is going well and fine, nothing wrong with the stairs or the bathroom, nothing wrong with my sims, until they suddenly all "break." My sims for an unknown reason cannot get into the 2nd story bathroom, they have the bubbly over their heads with the footprint image crossed out. I hadn't changed the bathroom from when I downloaded it into the gallery. My sims were able to go into it, and then suddenly unable to. My sims have a study on the 3rd floor. My sim was working on his computer on the 3rd floor when he went to work and came back that same day he couldn't go up the stairs anymore. I had added things to the study days before this happened, so he was going up and down the stairs peacefully. He was even teleporting there (since he is a spell caster) just fine and will no longer teleport up there. After the 3rd-floor glitch started occurring, the stairs to the 1st floor started to bug out as well, and my sims weren't able to go upstairs after that. I even disabled the mods and cc to see if it was the problem, but the problem was still occurring. I am very confused. Please help?
I will post the build in the gallery called: Wizardly
Thank you
