Multipliers aren't calculated correctly

It's important to remember that all the multipliers are cumulative and not compounded.

This means that every increase in the multiplier is applied to that specific multiplier, rather than the current outputs. 

As an example, if you apply a multiplier to increase your profits from x0 to x3, then you get a total x3 profit boost. If you apply a x3 profit multiplier on top of a x100 multiplier, the original number will be multiplied by x103 rather than x300.
