I noticed this happened to me last night in a huttball game. The only time I've ever experienced it.
Conditions: I was a Rotworm, the score was tied 1-1, and I was holding the ball as time expired. We were given "VICTORY" but the actual counter for my WZ wins did not go up.
What other specific instances are people having it not tick up? I mean I can understand it if it's a tie score in Huttball when the time runs out, except I'd love to have a sudden death portion where the last team standing wins the game in a pool of the enemies' blood. It seems the "Hutt" thing to do.
