Just what the title says.  I was playing a quickmatch (which did start this time, at least -- didn't go into a skirmish), and before either of us founded, I got a notice that I was bought out by PlayerX for 0.00.  PlayerX was, of course, not the name of my opponent.  If I cared about my standings, I would note that this did seem to actually count as a loss in my standings.

Likely relevant section of log:
