I’ve noticed throughout the past few seasons sometimes my gained pattern progress for weapons would suddenly just disappear, the first couple times it happened I thought maybe I just mis remembered things and would brush it off but now it’s become plainly obvious it’s an ongoing issue (may only effect Deep Stone Crypt weapons). Last season I only needed 2 sword patterns even though I knew I’d probably never use it I farmed boss during the weekly to just get it craftable anyways so I’d only need to get my final weapon (Posterity), just to check and see that now I’m back to 3/5 on the sword pattern. I wanted to get the Posterity craftable which I was 3/5 so I did final boss, bought it and extracted the pattern making it 4/5. I got off a couple hours later just to get back on today and notice it went back down from 4/5 to 3/5, I have no idea what to do about this kind of issue as I obviously don’t want to have to regrind patterns farming bosses or waiting for reset every week. Also yes I do physically extract patterns still though it shouldn’t matter I still do it anyways.
