Sims freezing in self-made CAS

[boeketjebloemen]

Hi,
I tried to make my own CAS yesterday, and completed it today. But somehow, when I make a sim with it, the sim is freezing. It's constantly rubbing his/her hands together, and making the "I'm cold" noises and stuff. And I even saw a wolf pack-leader in CAS once.
So somehow the game registers my CAS as outdoors, when I double-checked that it has "4 wall and a roof", so it is indoors. Does anyone know what I'm doing wrong and how I can fix it? It's irritating when the sim bows to warm itself when I'm editing something in their face, because they duck out of the picture.
I'd really appreciate some help!

Thank you, I should have looked better before posting.
