For highlight bonuses sometimes I get the most deaths bonus, when I have 0 deaths and everyone else has at least 1 death or more.

For me, the most consistent bonus that I get from the game mode, plunder ball is most captures. Otherwise, bonuses sometimes pops or doesn't pop in this game mode or the other game modes.

Overall, this will be eventually fixed and this is what the beta is for, to find any problems and rectify them.
