Why does keep inventory have to disable achievements?

There is a chance that your achievements are disabled for that world, if you installed a mod or enabled cheats to turn on keep inventory or similar things they will be disabled in that world permanently, unfortunately there's no way to fix this without
starting a new world altogether, if this is the case there isn't much that can be done sadly, you can check if achievements are disabled by opening your game settings while playing in your world, if they aren't disabled then try uninstalling and reinstalling
minecraft. It should keep your player data, I hope this helped!

You guys are not alone. I have run into this issue as well. Starting a new character does not allow achievement items (Battledress of Provocateur, High Regard of House Dace, etc.) to be placed in inventory. I have no idea why. It must have something to do with EA shutting down the DAO servers around 10/20/2022. I have a couple of saved characters that were started before 10/20/2022, and they have all the achievement items in the inventory still.

If these items are tied to achievements, shouldnt they just unlock if I have already gotten the achievement? Have you guys tried replaying Leliana's Song or Golems of Amgarrak to see if the items will unlock again? Let me know. I will keep everyone posted if anything changes on my end.

It's on the XBox so no mods (I don't know if you can but I know I haven't) but I did find the "cheats enabled" and I don't know why. I've never done anything with cheats, I would just use a creative world if I wanted everything.

So, because this got ticked in my world somehow I'm screwed? :/ I have years on this world, I'm not interested in starting a new one.

Sadly you can't reverse it to get achievements, but you can still have fun on your world and if you ever want the achievements you can start a world just for achievements, I know it's not a very good alternative but it's about all you can do, sorry.

They're achievement notifications? That's... why did they make them achievement notifications?

I guess I'm fine disabling all achievement notifications, but my preference would have been to disable this one very annoying, very prolific notification.
