Pack Version:
dev 54af4b7

Description:
The basic speed upgrade claims to increase machine GP usage by 1, but actually doubles the consumption.

Expected Behavior:
Increase GP usage by tooltip

Steps To Reproduce:
Insert a basic speed upgrade into the resonator, watch the GP consumption increase by 100%. If you insert 4, it is increased by 400%. 80GP is a LOT for players who doesn't have access to dragon egg mills, and without the speed upgrade, it is just painfully slow.

Crash Log:
If your client crashed as a result of this bug, please upload the generated crash log. This is found in your launcher's Omnifactory profile (aka instance) in a folder called crash-reports. If there was no crash, but instead an error screen, please upload your latest.log instead.

Screenshots:

This is a cosmetic quirk that we have no control over. The tooltip seems misleading but isn't, GP just has convoluted mechanics that aren't very transparent to the player.

Speed upgrades, like many things in XU2, have a diminishing returns formula applied per level. You can see how it is computed here, and this is what's reported in the item's tooltip.

The resonator doesn't use 1 GP more per speed upgrade to progress, but rather it advances by 4 GP times 1 plus the number of speed upgrades inside of it code here per tick. As far as I can discern the amount of GP required to complete the recipe itself does not change but the machine reports the progress and maximum rather strangely (code here).
