I've had that with some too
:(
Got a screenshot from earlier. Just for you
;) It did the figure of 8 for hours, went around 5ish times then I assume went to land somewhere. Didn't seem like an emergency that one.
And I had a 7700 alert from another plane but when I checked it it said 7000. Either a short emergency or a mistaken squawk code.
