Tournaments not working correctly

I've still got issues with tournaments not behaving as they should.

Take a look at this screenshot:

Mark.B played Remko......Mark B plays first and gets a PM saying I have advanced to the next round. Then Remko plays, beats Mark B, and Mark B gets a PM saying he's been knocked out.

Now Mark.B and Remko are BOTH on the next rung, but both showing as eliminated.

This can't be right, and it doesn't happen all the time, but some combination of events is sending things awry somewhere.
