This bug was fixed in Patch 1.97.42/1.73
My Sims is pregnant and she does has an Eating for Two! moodlet but that is missing the timer.
The pregnancy doesn’t advance and my Sim is stuck at not aging.
There’s currently a LastException in the game that is triggered when loading a household. The household isn’t loaded properly because of that exception and that leads to the issue with the missing timer on pregnant Sims.
Not everyone has this last exception and it’s unclear what’s causing it but the game tries to set an relationship bit between two Sims of which one is no longer in the game.
[manus] sim_info_manager failed to handle on_all_households_and_sim_infos_loaded due to exception (AttributeError: 'NoneType' object has no attribute 'sim_id')
Traceback (most recent call last)
There’s one report that it helped to play another household until the Sim gives birth but that didn’t work in my test.
You can also try to load a Backup but since it’s hard to tell for how long the bug has been in the game, it might be too late for that.
