dpgen:one sub-task skipped after VASP crash

[ccchenjj]

When i am running 'dpgen init_bulk' at stage 3, a VASP job (the job has 15 tasks) was interrupted unexpectedly (node failure).
So, the job was interrupted at 'task 10'(no '_task_tag_finished' file was generated in 'task 10' directory).
Then dpgen re-submit the job, but i find that vasp skip the 'task 10',and start at 'task 11',Thus i have tow questions:
1.Why is this happening？
2.how can i make it start at 'task 10'?
