Tree's resources and quality per stage

[Keiriku]

Quote from ringofbrodgar wiki for legacy version: when a tree grows to its next level, it resources (Bark, Branches, etc, if any) get refreshed.
1) Does it happen in new version?

I remember that in legacy trees were growing in quality per stage(If I'm wrong, correct me please), now my trees in 2nd and 3d stages have same quality as in 1st.
2) Is there any difference in quality between 1st and last stages?

Hard to tell, non of my trees are fully grown, but their quality grow once in a while, started with ~9 atm ~15

I don't think there are "stages" for trees right now. Maybe they still exist on the server, but we don't see the,.

The data sent from the server is a linear scale from 10% -> 100% and that's what the client uses to display the growing tree.

I don't know about that bdew, I watched a rather specific progression over a week of what items a tree was producing as it grew up (spruce tree). It was about the height of the wall by the time I left that area. Maybe not stages since it probably differs per species, but there's something.

Never saw any quality increases though.
