Can't Click on Sim.

I've never had this problem until just now. I aged up my child to a teen and went into CAS to change her outfits. When I came back out of CAS I suddenly couldn't click on my sims anymore. I do have mods, but as I said, the game was running fine until I came out of CAS, then it suddenly didn't work anymore.

EDIT:

I tried restarting but that didn't help, so I kept playing, just having to live with not being able to send my sims go jogging or having to change using a dresser. Also nobody talked to anyone for a while, but thanks to parenthood I got a pop-up. After that was dealt with everything worked again, I could click on my own sims again. Super weird
