Can't Exit Emergency State

1. So I had 4 Deodorizer set as !! for sand delivery, but then set to priority 8 after delivery is done. But the "Emergency Item: 4" warning won't go away after getting out of alert states.

2. Many game days later, I had some tile construction priority set to !!, but after they are done, warning persisted showing "Emergency Item: 4" etc.

3. So I had to try to deconstruct those 4 Deodorizer, after that, I got this screen shot. Not in global alert state, no emergency items, but can't get out of alert state.

reloading game fixed it.
