I apologize if this is not the actual location for such reports, I could not think of anywhere else it should be.
And I put a warning in the title as it will speak of things in the Shadowbringers questlines.

On the crossover portion of the Main Story quests "Shaken Resolve" and "A Grand Adventure", the Crystal Exarch says that the castle we are headed to is on the opposite side of the Source. However, the location is found on the First.
It's merely an error in the quest text, speaking of the wrong world.

Obviously a small thing, but something that stood out to me none-the-less that I wished to bring to people's attention.
