The Confident mood over-riding an Inspired mood is such a killer during a challenge with time constraints!
I've recently had two sims who constantly offer other sims massages. During parties, during a homework session, while the other sim is writing a novel, and so on, the now-borderline-disliked sim will go over and either offer or ask for a massage. This causes the other sim to drop his/her queue.
During a party, for example, the birthday girl needs to socialize with guests for xx hours, but what happens? Right after she blows out her candles, I see her mother leading her off to the massage table. This annoying conduct even passed from mother to daughter, lol.
Or, I send the sim over to help her son with homework but I spot the two heading to a massage table because she offered a massage instead and the teen stopped doing his homework.
Apparently, when a sim offers a massage, the other sim always accepts, even if it will make them late for school or work. Grrrr.
I finally moved the massage tables to an inaccessible area of the roof (along with the bar and the fountain of mirth).
Also, it feels like my sims get Very Playful more easily lately.
