Overcollect feature was demanded when the new multiquest feature was introduced for FA, but it was neglected. Now with the new badges this request is makes more sense than ever, especially for VV. Since you can not plan what recipe you get in MA, fixing collection at 15 is more ridiculous, then the amount itself. But this applies all other volume based badges: the amount which is over the value required to finish the badge should count towards to the next badge. And actually it would makes life a bit easier (and therefore the game more enjoyable) if this applies to quantity based badges: you won't need to repeat "stop, open, collect, close" cycle for every badge, when production finished in several manu or workshop at once.
