What does this mean?
 
Your expedition found some fleet in perfect operating state. Unfortunately, no one in your fleet was able to control those units.
 
!? I had enough fleet slots to send more attacks so IDK what else it could mean.... Do i have to send specific troops on an expedition or something? Why does this game have no info!?
 
 
 
 
 
 
EDIT: Never mind I figured it out. it means that the fleet troops that I found I could've taken back, however they need to match the troops I sent.
 
So if you send 10 battlecruisers....... and you find a bunch of steal fighters, then you won't get them, but if you find battlecruisers you will.
 
I assume this is to avoid the complication of making an algorithm that makes it so you only find level specific ships.
 
This way if you send a bunch of fighters you won't bring home a bunch of deathstars xD
 
 
 
This is the answer, unless this is incorrect this post can be closed. Thanks to no one to answered :P

Thank you for your explanation. I've found it useful

same here

Addition:
It also seems you have to send MORE ships of any kind then you find.
Example: Sending 10 stealth fighters can not bring home 50 stealth fighters as far as I know.

yes and also no you can send your ships in expedition and can also find some ships there as well but you need also those ships in your fleet as well to completely get a hold of those ships which you have found in your expedition there as well.
