I have almost 200 hero spirit, so it should be 600% faster than 0 hero spirit.
But, I don't feel it's fast enough.
Is there a bug calculating hero spirit speed% ?
(Price bug)
If newspaper is 50000$ cash, it should be 5$ after manager upgrade (99.99% discount)
Bug 1 - it remains 50000$ after 99.99% discount.
so you can't buy a newspaper if you don't have more than 50000$.
Bug 2 - If you buy a newspaper, it only cost 5$.
