Vaults and upgrades
I want to know something about the vaults, on level 24 you get 1% extra credit consumption, you can see that by credit consumption under buildings.
Level 25 gives you another 2% credit consumption but here is the default, -1% + -2% = -3%, so the vaults should give -18%, but it gives only -12%.
The vaults give per level 24 -1% and level 25 -1% and that is -2%, where is my 6x1% that the vaults should give ?
Level 26 also gives -2% per vault, do i get that or get i also a 1% bonus per level ?
Otherwise its not interesting to put money in the game for things you won't get.
