Finished one playthrough and went scene hunting. During that time, I found one error, which I can't recreate because it happened only once when I clicked on the emblem on the dwarven map, I missed the error message because I was spam clicking the map looking for secrets, and accidentally closed the error(whoops). Even with the error, I did unlock the secret scene in the album.
There is also a small typo in the text during chapter 3, when Zu-Dee says, "Impressive... I didn't thin(missing a k) Elves and Dwarves..."
Other than that, I found no other issues!
I am still missing a few regular and secret scenes. One addition I would like to see to the album is when a secret scene is unlocked, the album shows that it was a secret scene even after it is unlocked. This would help me see how many secrets have been found.
