Ultimate Function Pack

This is a data pack I use just because it has everything I need like night vision or speed...

Type "/function ufp:install_test" to see if it is working correct.

There is a small starter kit that can be used to skip a couple of minutes in survival.




This data pack will most likely not be updated a lot, only if there is a good function I can put in it.


Question:


The command : "/function ufp:unlock_advancements" completes all the achievements, right?

Now if I want to undo this process or just restart all advancements, how do I do that?
When I do "/advancements revoke @a everything", it just deletes the advancements and says "there doesn't seem to be anything here :(" .

Can someone help me with this please?
