Stack in the quest "Shura's past can be recalled"

[canmio3]

When I was doing this task, I was delayed for some time by other things, which caused the transformation effect of the task to disappear. But the task did not fail. I tried to switch channels and leave the shura map, and the task still did not fail automatically. Now I can neither complete the task nor cancel it.Dear GM can you deal with it?
