[GRO] Sit Up’ Milestone Stops Other Milestones From Unlocking

I don't understand what exactly has been fixed in the new update. In the article about milestones, the player points out the problem that “milestones are not counted after the infant got a milestonesit up .” But at the same time, they are fixing  ‘Sit Up' Milestone now properly unlocks and displays after travelling.... so the problem was completely different? That after receiving the milestone sitting, no other milestones are counted.
This also happened to me; after the milestone sit up, no other milestones were counted. In the video, you can see how the child reaches a new milestone and glows. The parents also react to the new milestone and take pictures. But no notifications of the new milestone appear, and there are no new milestones in the menu.

No mods. Vanilla game.
