What he means is that someone should have got the crystal and the other ally, the conquer. In his case one player (his ally) got both.
I have also run into this issue today.
My teammate and I launched at a colony with two crystals.
There was an initial difference of 11 tanks in our armies and after the battle there was only a difference of 9 surviving tanks in our armies (in my favor).
In theory I should have recieved 1 crystal, while my ally also should have taken 1 and the conquer. Instead I recieved both as well as the conquer.
How do you explain this ?
I have brought this up in my post in the community suggestions found
here and I believe the wiki should be updated with correct outcomes.
