Old achievements

this is fantastic! thank you for updating it to 1.21 :D
I will suggest adding a new "base" achivement to the tree so that the category isn't just listed as "Taking Inventory"

The ‘Overkill’ challenge is bugged, as it also includes indirect damage that has not been dealt by the player, such as ghast fireballs and TNT.
I’m not sure if this is just on servers, but the ‘Taking Inventory’ achievement just appears without actually going into your inventory
Also for the ‘Cow Tipper’ achievement the description is the same as the ‘Monster Hunter’ achievement.
Other than those, it’s a really great data pack. Have you ever considered making it so that it doesn’t duplicate the achievement message in chat for achievements that are spelled exactly the same and you do the same thing to get them, e.g Aquire Hardware and We need to go deeper

sad to report that seemingly as of 1.21 this no longer works, which kinda sucks honestly

does this add them in a seperate tab? or does it replace the ones already ingame?

Hi, when I try to use this in 1.16.5 it pops every single advancement when I pick up a wood log. Any fix?

Friend, could you please update this great datapack to 1.20 pls?
