Pending task in queue will not change status automatically[v1.2.0]

I got the issue when I upgraded to v1.2.0,It works if I cancel the task and restart it.

I recommend searching the forum for existing issues, such as Pipeline doesn't start until stopped and started again.

I can confirm there are no known issues with Drone 1.2 since we run this version at and have not experienced any problems matching this description.

@bradrydzewski Thank you,I have found the reason , the process of build is not been stoped, it is my problem.
