As stated it the title. Before the birthday update we were able to see the remaining days until a Zoi would age up in his profile (see screenshot), when hovering over the aging meter. Now there seems to be no way to see that…
Is this a bug? Or is this intended? Is it the same for you all as well?
Hello!
In the “Zoi Card” of the Zoi, if you hover over that line you are highlighting it should still tell you exactly the number of days the zoi has left before the next life stage(it is still showing for me.) so it looks like this is, indeed, a bug!!
Do you have any mods? If you post a bug report let me know so I can further help 
I noticed that now it only shows the days if I enable aging for the played family, otherwise they don’t appear, whereas before they were visible anyway.
Thank you @mialuce66 This is it! In the current save I had aging off at the moment. As soon as I changed it the days were visible again.
Never thought that this could be the reason as it was showing with aging off or on before the update.
Thanks for asking this because I thought my game was bugged too xD I’m glad that’s simply a change depending on our individual age settings
