Sim travelling in group by default (Can send home)

Since the most recent update I've had this costant problem that when traveling with one sim, the whole household automatically travels with him even if I didn't select them. I saw online that many other people are also having this kind of problem because of the new update. Can this be fixed?

I do have mods and have turned them off and still the same issues. They join right away. I can send the sims home, but not the dogs. 

Could you please provide the following information

• Are you using mods/cc in your game ? Please remove them and test without them if you do.
• Do they travel with you right away or join with a delay ?
• Can you send them home and if so, do they stay home ?
