First of all, I want to say this is probably the best new lands mod I ever played. I want that to be clear: I love this mod. Love the landscape, love the quests, and the dialogues, all that tiny little stories almost all npcs had to offer, almost all the voice actors are really good. It's top notch.
But! Now, some ugly things:
1) sometimes fast travel goes to black screens. I think it's because some loading screens added by the mod are failing to load, but I'm not sure. A small issue, but an issue nonetheless.
2) the landscaping is not perfect. It is awesome and detailed, but there are some rocks with gaps here and there, and some objects a bit missplaced (example: the stairs to Holly Falls never reaches the ground).
3) There are some doors not connected to interiors and/or some interior doors not connected to exteriors. Example: the door inside the Meditation Hall (or something like that) in Alinor Palace. If you enter that interior, you can't exit it.
4) I'm having constant CTD in the underwater cave under Solem's Pond (Shadow Pond Cave, or something like that). It's maybe something on my end, but as of now, I was unable to solve it.
5) The first quest of the Order of the Tainted Blood don't appear in my journal. I don't know the others, because I just did the first one. If that's intentional, it's bad, because if you forgot where Elara pointed you, you are blind. And my memory is not as good as it was hahaha
I'm enjoying the mod. This is just something like late test report, hoping it helps to make it even better.
