i found one bug recently, that can give you infinite amount of Maws. to duplicate Maws, you need:
1) buy upgrades 2 times and evolve Maw (upgrade to next tier)
2) buy any upgrade
from this point bug actually starts, it can be done any time if you have at least one Maw that wasnt upgraded further
3) click on evolve button (2, 3). sadly your Maw wont evolve, instead it will say that you didnt buy upgrade
4) buy any upgrade
5) look at your inventory
6) profit!
