Engineering 1-600 Step 40

[koolaider]

The guide asks you to create 100 gold bars, but it should be 10. A previous step asks you to mine 10 gold ore, and a following step asks you to create 10 Gold Power Cores which cost 1 gold bar each to create.

Sounds like a typo. I'll pass this on to our content team for it to get fixed.
