Last Stand scoring broken post-update
I played the Last Stand today after the update and found the scoring is broken. I made the same wave I normally do (Wave 20), but before the update my score was 16571 and today it was 6952, or not even half of yesterday. As a result, there will be no way to climb the leaderboard against those that played this week before the update. I did notice that after many waves my multiplier would drop, even though I killed walkers during that wave. I have submitted a ticket in game.
