The Bug:
When using command: /advancement grant @s all, Then using /advancement revoke @s all, The notification does not leave the screen but goes through all of the advancements, even when the have been revoked. This might be a bug and its a bit annoying so I reported it to Mojang. Can this be fixed?
Steps to Reproduce:
Give yourself all advancements by running the following command.
/advancement grant @s everything
Revoke all advancements from yourself by using the command provided below.
/advancement revoke @s everything
Wait around twenty seconds.
Take note of how advancement toasts still continue to appear despite the said advancements being revoked just previously.
Confirmed. I've altered the description of this ticket slightly for ease of reproducing the potential problem here. I hope this is okay. 🙂
