Unable to choose alternate career branch

@crinrict Perhaps there is a bug with in-game events occurring during a transition to travel or to manage worlds. Just a few minutes ago, I had one sim traveling home just as another sim in the household returned home with a promotion.  The notification popped up in the worlds view; "Traveling with...".  Fortunately, this sim is further along in his career track so there wouldn't have been any prompt for action.  These in-game notifications haven't been an issue before since I've only noticed things like mail being delivered.  

I get what you're saying that the lack of an option to change branches isn't a bug.  However, I stand by what I said before.  Going back to uni just to change branches is less than ideal.  I guess I'll just have to hope the developers change their minds and give us an option to change at any time. 

You're right about the demote cheat.  I went into an older save and tested it on two different sims.  In both cases, demote caused the sims to be fired (which by the way gave them both a 24 hour Sad +3 moodlet).  When I had them find a job again, the only available option for their careers was the level they had before they were fired.

Thanks again!  I really do appreciate your help.
