When a 2 continuously recurring task is scheduled in the grill, it is doing the first one continuously. The second task is ignored completely and so are the next items in the queue.
How it should work: first task, then second one and the 1st and so on.
If non-continuous task is after the continuous task, it should do once the continuous task, then non-continuous task, then continue doing the continuous task repeatedly.
Steps to Reproduce
have a look at the Electric Grill
