Why not allow, stacking?
Following with the example given; Invest 10 Kp to any kind of AW.
If you spend 100 Kp to any kind of AW, you get 10 Badges, instead of having to click countless time to add the Kp, then click on the 1 Badge gained.
And if there's no stacking, then spending a 15, 20 or 30 kp instant is a waste when used for Wonder Society badges.
Here's the answer that was given by the Community Manager "Marindor" on the beta forums:
Thank you all for your feedback so far! Regarding the questions about stacking productions and mass-collecting for multiple badges: This is not possible and also won't be made possible. Fellowship Adventures are something you'd have to actively/purposefully participate in. Therefore strategy and planning and communication with your FS should be required to work together on this effort. Producing particular badges should be something you're doing consciously. So you're collecting the things you need for a badge, then wait for the badge, and then collect your next badge (if you had a few running simultaneously). We want it to be something you're actively engaging in and thinking about, instead of just collect everything at once like you'd normally do and just start new productions.
Without stacking, the end result is the same, just with more unnecessary clicks. We still have to plan what we're making and participate as a group. If I have 50 little workshops cranking out toolboxes, I still get 10 badges. So why is it necessary to make me stop after every set of 5 (hopefully without overcollecting by accident), open another window, claim the badge, close the window and then resume the next collection, repeated 10 times? The only drawback I can see with stacking is that it could make the goods portion of the spell badges inconsequential. For all other badges, stacking actually makes more sense.
With that said, this seems to be a vast improvement over the previous cycling experience. Still seems tedious, but much less so than before.
Another possible issue is now we'll also have to keep in mind how many of each thing we've already collected so we don't overcollect. I can tell that I'll be opening that window constantly to double-check how many things I still need before collecting from the workshops.
