CORE MOVEMENT
Because all resources and produced Y-Units are hypered directly to the Core, from time to time you will want to change it. After moving the Core, a recharge time is needed before you will be able to move Core again. To move it, just enter any valid coordinates (in open space or star system) where you have at least 100 Y-Units in the idle mode.
Y-UNITS & ENERGY PRODUCTION PRIORITIES
Here you can indicate in % "the maximum allowed" usage of Metals from Core. If you set respective value to 100%, this mean that CF "eat" all Metals for Y-Units production. Take care about insufficient resources, because you need Metals and Energy for units maintenance.
Crystals are used only for Energy production. So, if you want to sell a half of mined Crystals on the market you can set respective value to 50%.
