ADDON VERSION: v40

Describe the bug
Ancient Hornswog map icon is not displayed despite having rewards that I still need. I have tried changing the options to display all rares regardless of rewards etc. and I simply can't get this rare to show.

I have tried with all other addons disabled and I can see in the code that the specific dragonriding glyph that I'm missing is marked as being a reward from this rare. So I have no idea why it's not showing.

Apologies if I'm doing something wrong or stupid but I'm concerned there are more rares / nodes that aren't being displayed that I have no idea about.

Edit: I'm dumb ignore this
