I’ll make a recap of my experience with track archives as well as a separate description.
I’d say exactly the same issue as disabled tracks internally in handling - something gets out of order - as it does for disabled tracks when restored.
#1. Not creating a good track archive
a) from a fully featured project I save superiordrummer instrument track as track 29, and a group channel for it on track 33 and save those two as selected tracks.
b) as restored you get outputs scrambled order, sometimes not colored as instrument track(red in my case) and a bunch of extra automation lanes which in some cases can be removed, sometimes not. If colored gray they could be removed, if colored red as instrument track - it could not be removed.
c) in some versions of Cubase I also got popup dialog about missing tracks etc when restoring an archive.
#2. Workaround that seem to create ok track archive
a) make a blank project, and just insert superiordrummer and a group channel for it - and save those two, track 1 and 2, as selected tracks.
b) as restored into any project seems to work ok, all named, ordered and colored and no extra automation lanes.
So there seems to be confusion how Cubase handle things and keeping what belongs together in order.
