Meh. It aint something that's bothering me. I just noticed it and it kinda stuck in my head.
I still didn't figure out the artifact stuff for Al-Simhara Egypt. I guess I'll need to find a detailed walkthrough or something. In China, I found most of them (on other neighbourhoods). And France, why would I want to go there? I hate France for that anoying mansion. Only contained some grapes.. ahh well.
Now something I never figured out.. do you always keep a raise? Like I get a 3 simdollar raise for science and the next day I get an promotion. Does the raise also get counted in by the new salary like instead of the standard 33 now 36?
(Never done science, so this may not be accurate, but it's just to help you understand my question. If that's possible with my writing skills, heh.)
And to ik, I'm not sure to who your question is mentioned, but you can switch families through town edit switch active household (which I'll never do again. Turned off story progression, but it kept running while I was busy with my painter [just to have a new Sim in town]) or through the main menu, different neighbourhoods.
and.. mostly my sims that are in the same career are also generally in the same family/household but i tried to add 2 new workers once though from another family for funs i hope this calrifies it if not ill try to expain/tell it more readable? ( i really need to figure out how to use stuff like dots lol just cant understand how it works =p )
