I was playing against AI 1vs1 (Advent vs. Advent) and after I have got a Military Victory screen an enthusiastic 8 year's old announced that "The Unity is Victorious" and it appears voice-over simply did not want to stop - it was playing on the loop after I have chosen to Keep Playing.
There was also a constant message (above the info-cards in lower left corner) saying a "String is Missing" (it did not disappear).
