Because Kubejs does not, the task expansion and unknown MOD conflict, so I tried to find such a method with group friends (but it looks like a bug):

First create a task, where the granite is used for granite.

Right -click the task to find [Copy ID] to copy the task ID.

Then add a command reward:/ftbquests change_progress @P Reset task ID

Set these two rewards to automatically receive.

Then I made great achievements.

After the first collection, the command reward may be displayed.But this does not affect the repeated feature of this task.
