I downloaded the new pack and now the game is so bugged it’s unplayable

The spin class has no animation and produces no funds, none of the sims can paint or do pottery during getaways, the lifting weights interaction is bugged. My sims won’t sleep, they just keep immediately waking up and standing next to the bed, no tv or radio on. None of the sims actually do the activities they’re supposed to during getaways if the N.A.P. activities conflict with the lot activities. The half the guests that aren’t baking random cakes are just standing in one place until they pee themselves or collapse from exhaustion.
