Lets say I have a few achievements already unlocked right? Can I unlock some and move the ones I already did unlock around? Or even just relocking them would work too. Thanks for any answers.
I don’t think relocking works. If you relock them then MS will notice somenthing wrong with those achievements and probably ban you.
This is correct, relocking achievements isn’t possible. As far as rearranging them, if you’ve connected to live it isn’t possible to rearrange them.
