I beat the game but can't go here cuz can't buy this key again so is it 1 one more area and we're need a hotfix version where'll be able to buy infinite count of keys I suppose? If I'm not mistaken I accidentally bought this key and sell it so my mistake but it's pretty long to pass this game again and for the people that could make the same shit it's better if the number of purchased keys would infinite or smth like that. Or the most easily to make a full save and post it in f95 or Discord:D
Edit: I'm blind so the key left in the buy menu of the blacksmith
