With the last update he moved up to a toddler for me, luckily it doesn’t affect anything else. I’ve had more babies since and they have grown up. Hopefully with another update he will grow to be an adult and I can move him out. But he won’t on his own.
We just had an update mentioning a fix for this issue, please update and check your games:
Let me know if it's fixed, or not!
