Ordering the TK to "refuel from own tankers-Saturn" means, when at Saturn refuel from tankers in your task group.
To do what you are trying to do you should do the following:
1. Order TK task group to "unload 90% of it's fuel on Earth"
2. Order TK task group to refuel from FH task group
Mark that to repeat forever and you should be good to go. You can put those orders in in either order and it will work.
Sorry to necro an old post but I have the same problem as the original poster and this solution doesn't work for me.
I have a harvester sitting at Saturn 100% full. The only option I can find to do #1 is "unload 90% fuel at nearest colony within 4 jumps" (this is a "conditional order" It was the only one that looked remotely like the one quoted above. . . ).
For #2- From the TK grp, I select the harvester from the "available locations" list. However, I DON'T get an option to refuel from the harvester grp. The only option I get is "refuel target fleet" or "refuel from own tankers". ( I tried doing the actions separately, trying the "unload order" first but nothing happened).
Any idea where I went wrong ?
Any help would be appreciated
EDIT:
Wow, I know i looked for "unload 90% fuel to colony" a hundred times!!! Of course, I find it after I post this...
Still, I don't have an option to " refuel from harvester". My TK is still at Earth but with 10% fuel. How do I get it to refuel from the harvester?
