    Is there a way to maximize your chance of getting the special resources per bubble? I click dozens of them to get any one item, and once you get very far into the game, increasing your storage or unlocking expansion slots is prohibitive. I won’t even get into the ridiculousness that IS the global trade HQ. I don’t even bother going there for anything anymore. There need to be some tweaks.

    At what level does the bubbles/global trade start to give you expansion products?

    The chance you can get these special resources aren’t equally divided, right? I’m at level 14, and trying to expand my city. After some days, I got 14 dozer wheels, but only 4 dozer blades and 2 dozer exhausts. The same happens to Storage Cameras… I had 10 of them, while just 5 bars and 3 locks.

    Im at level 40. Nope you get from bubbles what you get. If you got 10 dozer wheels and only a few scoops then sellsome off the dozer blades etc. Eventually you will get what you need. But it may not be right when you want it. Its a great game. Just have fun.
