Page needing to accept updates from itself?

This seems to be relatively new and I’m not sure if its a bug or a feature. In the past, all your instances would update in real-time as long your main component was on the same page. Even if the instances are nested in some other components (also on the same page).

Today I made some changes to my main components but the instances were still stuck on an older version. I had to manually update them even though all of the main components were on the same page. Anyone else experiencing this??
