I thought maybe it was an addon conflict,
BUT I disabled all of my other addons and libraries and Destinations still did not show bosses on the map for group dungeons.
I've checked my settings over and over, and delves and public dungeons show the bosses on the map, but group dungeons do not. I know they're supposed to. Maybe not for all dungeons, especially the newer ones, but definitely for the much older dungeons.
I even tried reinstalling Destinations.
Has anyone else ever had this issue? Does anyone else know of a fix or some steps I should take to try to rectify or troubleshoot the issue?
Edit/Update: So... apparently, Destinations doesn't, and has never, marked bosses in group dungeons. I guess I must have had a different addon a long time ago that did, but now it doesn't exist anymore. Lame.
