I just finished a skirmish of my mod Star Strike, or thought I did. I wiped out the AI's base thoroughly and it went Braveheart with the rest. Wiped that out, but the match didn't end.
I killed a few stragglers, and it still didn't end, so I map snapshot feature to find out what I had left to kill (it was 1 on 1)
In the YRM map, under aircraft, I found 3 remaining units. SSSBOMB is a stealth bomber, nothing too special about it, it drops bombs and is radar invisible.

I took another map snapshot a little bit later...

And they were seemingly moving, as their X/Y coordinates had changed.
Do you have any ideas on how those bombers were created? Did the AI build them, were they called in by a SW, by a map trigger, something else? I assume you had Short Game off?
