Downgrading/Upgrading Adv Mats Collapses Everything, Losing the position

[dense tundra]

I just want to say that I love the new Materials panel that's organised by season as well as putting the trinkets mats separately. Excellent work.

However, with every improvement often comes a new bug (unfortunately).

Basically now whenever I downgrade (or upgrade) any advanced material in the Materials panel, all the categories will then collapse and I'll lose my position.

Again, I have to commend the work on organising the Materials panel but this bug has to be addressed as well.

This is even worse when we want to downgrade multiple levels (let's say fine quality to poor) , the categories will keep collapsing after each downgrade.
