It just seems very limited that you only use your crew to raid areas near water. Can this be upgraded to do raids on some forts on land. I only repeat 4 areas because they have the most people.

I've watched all the vids I can find, read what forum posts I can find, and tried to light all 10 braziers multiple upon multiple times, but the fires will not stay lit.
Is there some trick to getting them to stay lit? Starting from the fast travel point at the tower, the first one lights fine. As does the second. But by the time I'm at the very next building, the first brazier goes out. I'll stay "on the wall" as much as possible, jumping as needed. I've tried walking around the stones into the snow, and can even walk with the camera backwards and I can watch the first brazier go out...every time. Continuing on, thinking it might just be the first one with the problem, the 2nd brazier goes out as well by the time I'm a similar distance out again. I'm not a massive trophy nut, but this all makes no sense to me and I'd like to figure out if I'm doing something wrong. (in case asked, yes, I've gone out to the animus and come back, yes, I've 'restored the licences", twice now, and yes, I'm certain I'm trying the ten proper braziers, including the last up the tower by the corpse". They all go out when a certain distance away is covered. So please, I could use some help. I feel like I'm missing something but can't figure it out. (oh, and I'm on a ps5).

Exactly what the title says.
Look, I'm loving playing Valhalla, I truly am, but it's hard to not be frustrated by how unpolished this game is.
I'm about 80 hours in the game and just now I've noticed that the letters sent to us in our settlement aren't just cute updates from our allies, but that they may actually lead to extra scenes when we visit them in their respective cities.
Valhalla is a huge game, with a lot of characters and loads of stuff to do. I always read the letters, but to be honest it is kinda hard to remember every city I visited, specially if I had done that dozens of hours ago. So, when I noticed I was missing things out I went to check my inventory for the letters I've read but I couldn't find them. Why? Did Eivor throw them in the fire or something? It makes no sense the letters disappear immediately after you read them once.
I don't mind that these extra bits of story are not tracked (I actually prefer it that way), but it would be really, really helpful if we could just access them later (without having to resort to printscreen). Or am I missing something?
