I'm with Joeclark on this one, unless I've been doing this wrong.
THe only way I can load up my mineral-less colonies is to dispatch supply ships with the order chain:
- load duranium 2,500 on colony earth
- load neutronium 2,500 on colony earth
- load corundium 2,500 on colony earth
...
- Unload all minerals on colony titan
- refuel from colony earth
[repeat]
and that all get tedious to type in.
At the very least a "load 1,000 of each type" would be nice.
The problem with this approach is that it breaks if any of the minerals is unavailable. IE it breaks and you have to re-issue the orders every time. (If you had a surplus of every mineral on both planets, there'd be no reason for the cargo route anyway.)
Sounds like the functionality I'm looking for is already in the game though, thanks to those who pointed it out!
