When it happens to me I still quit out, in the amount of time I'd get to be sitting there doing nothing on a black screen (for a consumable pack worth of bonus coins), I could have already loaded into another game actually playing. Since it's been reported to occur as early as second objective, that is alot of time to sit on a black screen not playing just to be rewarded for their work, if you can call it that.
In the end I guess it's up to each person, what would you rather have playing the game or a reward.
