I don’t know if it’s by design but I have noticed that whatever the requirement that is needed to level up, the Sim will get a number of the required items but not all of them. When my Sim starts her profession the next day they have to start all over. They aren’t receiving credit for the ones they received the previous day. I’ve noticed it in the Movie career especially. Like I said I don’t know if it is by design but it is really frustrating. Most of my Sims have been at max career levels for a long time. I didn’t notice it happening when I leveled up Sims in the Spa Career. I just so happened to move a few Sims to new careers and the Movie Career is one that I accompany them for a work day. That’s why I noticed what was happening. For the other careers that we can’t go to work with them it isn’t as noticeable.
