cc @JLGarber who mentioned something to me about Titan story mode.

[JLGarber]

Yes. I've been through most of this content so far and didn't notice any discrepancies besides Titan, but I can check through some of it during the long US holiday. My gut feeling is that most of it is fine with just a small number of actual changes. (Stone Vigil's second boss is completely different, for instance.)

[JLGarber]

Haukke Manor and Stone Vigil can be trivially marked as okay. They have no timelines, and the triggers all seem to be working.

[JLGarber]

The Vault seems fine as well. There was an actual change to Grinneaux, in that Faith Unmoving had an indicator added, but the action ID hasn't changed.

(It looks like I never added a trigger for the Holy Chains mechanic on Charibert though. Oops! I'll look at adding that this weekend.)

Sirensong Sea, no changes needed.
