The Sims 4's High School Years update has added some deeply unfortunate bugs

rockpapershotgun.com:

The Sims 4 High School Years is launching today, but its release looks set to be overshadowed by a couple of major bugs introduced by its supporting update, Patch 132. The patch came out on Tuesday and, if you've played The Sims 4 since then, you'll have automatically downloaded it unless you've been playing offline. While the patch's release coincides with the High School Years expansion and supports a number of its features, it also added several new elements to the ever-evolving base game. These include long-time fan requests like sexual orientation customisation, body hair options, and the return of a wants and fears system in the style of The Sims 2.

Unfortunately, as is often the case, some bugs reared their ugly heads not long after the patch was released; and on this occasion, the problems they cause are hard to ignore. For one thing, it seems The Sims 4's infamous "incest glitch" is back once again, almost as quickly as it was last patched out, with the new wants mechanic causing teenagers to develop a desire to date their favourite siblings. It's not a good look, although mercifully so far it seems like toddlers and children are at least being left out of the unpleasantness on this occasion.

One thing younger Sims aren't immune to, however, is the rapid ageing bug which seems to have affected all save files using "short" or "long" lifespans, which are available as part of The Sims 4's gameplay modification options. Instead of their age counter ticking up once per in-game day, Sims in these saves are ageing much faster, and the unnerving result is a cradle-to-grave cycle that can last just a few real-world minutes.

Luckily, there's a work-around for the ageing bug, although it's not an especially brilliant one.
