The Sims 4's rampant pregnancy bug was apparently caused by 'performance optimizations' and has now been fixed

The baby boom is over. EA has neutered a bizarre bug recently introduced to The Sims 4 that erroneously marked Sims as being pregnant, irrespective of whether they were male or had previously engaged in 'woo-hoo'.

The bug initially appeared last week, slipping undetected into the game in a base game patch that coincided with the launch of the new Enchanted by Nature DLC. The bug indiscriminately identified random Sims as being pregnant, while also seemingly breaking everything else related to pregnancy.
