Continuity error with Harding

There is a pretty bad continuity error regarding the order of unlocking Solas's memories and what Harding and the others know about the Titans. When unlocking the memories before having done the companion quest "The waiting stone", Harding reacts with knowledge she is not supposed to have yet. Besides this causing the continuity error, it also spoils the reveal of this information that isn't supposed to be learned about until later on. 

The obvious fix for this would be to lock the memories behind further progression. So it wouldn't be possible to see the later ones regarding the Titans until said knowledge has been gained in the story. 

As a side note, the entirety of the lore regarding Titans feels very rushed and has a very weak delivery. If any parts of that have been cut, I would definitely recommend patching them back into the game. During the narration of Varric at the end of the companion quest, saying how Harding was disappointed, all I could think was "She isn't the only one".
