Black Feather Wings Glider still broken
When I unlocked mine, I was not wearing it. It was just in my inventory.
I also went to the 1st scout in Verdant Brink, at the entrance. You must watch and WAIT through his whole spiel, DONT skip any talking. So you must wait through all his “go here and do X” and “The Pact needs your help” stuff.
After that he will give you the option.
Nope that doesn’t work either. Just tried it exactly the way you described both with it equipped and unequiped at the same scout. I have never skipped any of the scout talking part. This is just plain broken for me.
