I know Twallan used to warn of strange behavior that could happen if you lowered the game time speed too much, but half speed was always safe and that's why I chose speed 50 for Sims 4. I used NRAAS Relativity in Sims 3 and I was so happy to see that kind of option for Sims 4.
Relative time speed should be like it says: Relative. I'm so confused though why this would happen, because in the past before Deaderpool removed the option, it was Absolute time speed that would screw up the internal alarms in the game, because of how it worked.
It sounds like there's definitely something up with the times not syncing correctly with the gigs in the acting career, so I'm going back to default speed after all, simply because the freelancer careers rely on the same gig system design and I've been hoping Maxis would do something for other careers using that system since Get Famous was released.
Thank you and for your input! Much appreciated!
