Amonia Leak invisible

Quote from PortuguesDC

I'm not sure if it only happens to me but, for some weird reason I always find that the Amonia Leak call is hidden on the missions list and I can only see it (on the list, on map I'm not sure) either by refreshing the page or by sending vehicles to that missions by accident (to be clear, I mean by dispatching units to the Amonia Leak after using the "skip to next call" button and finding this "hidden" mission).

Thanks in advance, have a nice weekend

I've had this with several types missions over time, the issues come and go over the weeks and rarely persist. But it's be interesting to find out what's going on with the calls when they do this.
