When right-clicking on a key is supposed to open the map for the waypoint, it’s been broken for quite some time. I couldn’t find a bug report on it so if there was one reported please forgive me.
When I right-click on a key it doesn’t do anything. I have to first open the map (M) to see the waypoint I’m supposed to go to in order to use the key, I can then close the map and right-click on the key and it opens as intended.
