On my main character, and my second character... the minimap, and the map completion list on the left of the screen, appear to suggest I have 18/18 Skyshards in Solstice.
Now, as we know, there are 9 Skyshards in Western Solstice... and 9 more in the East.
Now... I have never been to Eastern Solstice. It hasn't opened, and I did not ever go there (either by accident or on purpose) when it was incorrectly possible to do so.
So I have not picked up, or even found, the 9 Eastern Solstice Skyshards.
I do not, for similar and obvious reason, have the Achievement marked off for having all the Eastern Solstice skyshards...
...So why does the minimap list think I have 18/18 instead of 9/18?
And what's going to happen when I actually find them for real, once Eastern Solstice *is* accessible?
