Quoted from FatPanda:One request I have for Eric is that when you're in MB and a mode stacked, there are not Jackpot callouts. Would be nice to still have Rick give us Jackpot callouts so that we know when we've hit shots.
Because of the stacking, this is problematic. In the next update there are light shows that go with the jackpots, and the callout will play - IF the shot doesn’t trigger something else for a stacked adventure first.
