Yesterday, I played on my hardcore world for almost the entire day, so I closed the game, got up, and turned off my pc. So today I wake up, do what I normally do in the morning, and I booted up Minecraft. I had some things that I had to do in my hardcore world so I opened it, and I was going caving at the time, so I decided to kill a spider, and to my surprise, in chat, it says, "GGamer357 has made the advancement 'Monster Hunter!' ". I was confused, so I went into my advancements, monster hunter was the only one completed. At this time I had full diamond armor and I was getting ready to beat the ender dragon, so I had lots of achievements. I saw another bug submission on this, and it said it was fixed, I'm here to say, it definitely isn't.
