Bank's

No we know the game still working after the demise of flash. The next issue to sort out is the BANKS? In the last so called upgrade all buildings was possible to upgrade to level 30! But with the BANKS this is not possible? WHY?
Noticed it as well
Well banks nearly full; which means I be starting to use stadium to store cash! All because the idiots decided not to let us upgrade them to level 30 like the rest of the buildings just don't know!!!
Still no sign of bank upgrades so can't spend any money or collect it any more SN are useless!!!!
also just discovered you cant save extra cash in your stadium!!!!
