This isn't actually a bug, it's more of an annoyance so I'm posting it here.
Here's the issue: when you're doing quests in Solstice and you are in some district of Sunport, if you zoom the map out to show the whole island (to see where the quest is taking you) the map doesn't show the quest marker - it just shows the door you have to go to in sunport, to exit. To see the location you need to exit Sunport entirely and then look at the map.
Maybe an example would make more sense: So I'm starting the quest "The Gift of Death". The quest is given to you in Vinutilmo Palace. The quest task says "Go to Corelanya Crypt", but if I open my map to see where Corelanya Crypt is it shows me a map of Sunport with the door of Vinutilmo palace highlighted:

Ok, so then I exit Vinutilmo Palace and I'm standing in the Palace District. NOW if I open my map it looks like this:

So now I have to exit the Palace District. When I exit the Palace District, my map looks like this:

Then I take the wayshrine to the Sunport Docks wayshrine which is outside of Sunport, and now when I open the map
FINALLY I can see where Corelanya Crypt is:

But I had to exit 3 areas in Sunport before I could see Corelanya Crypt on the map! Is there some reason I can't just open the map and see where the referenced place is?
