We're looking into with Aerial Anomalies not being triggered in game. We apologize for the inconvenience. Further updates will be shared as they become available.
The current summer event directive line has been extended through July 5.
Aerial Anomalies will now trigger more often, but still only once per continent in most cases. This corrects an issue that prevented the event from firing, even under intended conditions.
This fix will go live tomorrow. Check the full patch notes here.
