Ok I lied. But it's something...unusual. Bags of flour stack now. So you can buy 10 bags and they come in a nice little stack of 10. But if you go to make something "You don't have the components needed to make that." So you have to double click the flour to turn it into an open bag. That's not the inter- err, unusual part though. If you double click a flour bag that is part of a stack you'll get 15 uses out of it. If it's by its self you'll get 20. I noticed this when I bought three bags of flour and stuck 60 tribal berries in my bag and only ended up with 50 paint, 10 extra berries and no flour. At GM with a tally that gets me to 100% success it had a me a little confused till I did some testing. Weird, eh?
