As the title says, the Heavy Blunt engraving not increasing after 50 kills. It always says 0/100, no matter how many kills I get. I tested it for swords and it works fine. It's not a really big issue but I really like that weapon type and this way I don't have a feeling of advancement and specialization. Hope this helps you in tracking down the issue.

P.S. the game is phenomenal, both beautiful and very fun.
