@kreutzgang I go under water and then just swing wildly at the fish. If you go to Wincestre and farm those rivers in the city, then you can get a lot of burbot fishing. Double spears is helpful.
My speculation is that this is probably a bug. I am on PC and have the same...and trust me, with over 250+ hours of game time, I have explored everything.
@draeoth I have also observed that I have 2 slots for this same armor. I am not sure when this happened. I am on PC.
@jesusalfn I am on PC and have this appearance issue.
Here are some screenshots of the merchant and my inventory.
I have observed that I have been allowed to purchase "The Mark of Sol" Predator bow from the merchant multiple times and it is still for sale at the merchant. This seems like a minor bug.
on PC, I have 1 hoard treasure in Oxe..shire and it never completes. I am allowed to keep getting XP for finding it.
I have this happen quite often. You have to restart to clear it.
