Might be related to queue reordering (I've moved REST tests to the top - no effect anyway).
Mate looking at the time lines of this, I don't think it's a bug, it might be late night at work timing issue.
First screenshot is possibly from:
where both 4227 & 4228 are queued & 4228 started @ 4:14 on an EC2 agent until:
and so the 4228 build was lost (expected behaviour), then you checked out the 2nd screenshot at possibly:
where 4227 is happily building on Panda and 4228 has gone offline (the error down the bottom) and both has gone out of the queue. I can definitely see how it could be a bit confusing but all seems to be working okay in this instance.
