Vagn’s weapons and foreign supplies are bugged. When I thought he had only 1 weapon left to buy, he actually had 2 available, one of which was a duplicate (in my case it was the Bálhrafn Scythe). I accidentally bought the duplicate thinking it was a new weapon, I had 1000 foreign supplies at the time, so minus 800 which is the cost of Vagn’s weapons, it left me with 200. After this I wanted to get the last 600 foreign supplies needed to buy Vagn’s last weapon, but for some reason when I river raided the game capped my progress at 400 foreign supplies. Raiding more places after getting 400 yields me only crafting materials.
When I went back to Vagn, his map showed that foreign supplies are “exhausted”, leaving me with only 600 in total, and unable to buy his last weapon which costs 800. This all leaves me with a duplicate of the Bálhrafn Scythe in my inventory, unable to buy the last weapons Vagn has which is (in my case) the Bálhrafn Atgeir.
Could you maybe fix the bug by reimbursing the 800 foreign supplies cost of the duplicate weapon, or at least uncap the total foreign supplies we can get from raids? I know that it’s supposed to say they are “exhausted” after buying everything possible from Vagn, (which I guess it’s what the game thinks I did when I bought the duplicate) but this type of duplicate weapon bug is so annoying that I think it’s better to just uncap the foreign supplies you can get than waiting for bug fix after bug fix.
