Should awards in arena mode stack? Because they don't. For example, I'll start arena mode, and it might say "Gold 150, fragment 0, points 1000" - then, at the next post-boss screen (eg, just after level 3) it might say "Gold 0, fragment 1/3, poits 2000" ... It seems to me like these should add, so that the further I get, the greater the reward. Instead, I need to choose - I can redeem and take the gold, or move on taking only the reward for a given set of 3 levels.
(It would also be nice if I could 're-roll' to get a better round-1 offer, but that one makes more sense as a deliberate choice.)
