I have a mom who's been carrying around a baby since yesterday. She's the first one I granted youth to (she's my first Devotion Master), and the only one this has happened to so far. She was well into her 40s before this baby came along (still don't have all the relics, so I had to wait for my population to drop low enough first). I haven't reset my computer clock (too lazy). I only pause it overnight or if I'm going out now that I've solved all the puzzles. I've tried time warp on her once, which aged her a year, but the timer hasn't changed at all. I've tried dropping a male villager on her, but since my population is currently maxed out, that hasn't worked. Yet. I've got some old ones that I'm waiting to die off & then I'll see if that works, lol.
