small border nitpicks

It's been stated elsewhere that bookmarks after 1444 are no longer being supported, so there should not be any changes from Paradox on these matters. I friendly modder, however, might take these issues under advisement.

That's not accurate. We don't balance for the later bookmarks but we do fix history bugs in them. It's just very, very, rare to get any bug reports for them.

Bug forum is however the right place for it

@PANGI I will be looking into your suggested changes. The color of the Salzburgian wasteland is automatic though and nothing we can do much about (and has no in game effect anyway).

Provence not being in the empire is down to how the HRE mechanics work in the game it's a conscious decision to have gameplay better reflect history even if the setup itself does not (and it's not the only such decision that was taken in regards to the HRE, you could argue the Teutons should be a member as well for instance, even if their lands should not).
Biggest reason for the state of Provence is what @Vaximillian brought up.

Decisions like that aren't always easy (and there are a lot fewer about than one might think), it's good to have them questioned at the various points of the game's existance but they are nonetheless the kind of thing we have to do sometimes

...and if you want another tiny spot on HRE face: Ruppin was independet county until Brandeburg seized it in 1524

This is actually in the game though covered by events. The Ruppin province is larger than just the counts domain though
