[Tuidjy]

I am positive that I have had this problem at least three times in the game I
just finished. I tried twice to GoR two lightning cyclops in one turn, and got
only one commander. The gems were spent, but the second cyclops stayed a troop.
Another time, I tried to GoR a healthy lightning cyclops, and GoR'd the
feebleminded one instead.

Afterwards I just stopped trying to Gor more than one per turn... and once I got
my summoning to six-seven tartarians per turn, I stopped bothing to GoR, either.

By the way, that province was shock full of all kinds of troops... only the
Tartarians must have been more than 50.

I just tested it. First recruited three units of the same type, and tried to
GoR them, but the list displayed only one. Then I recruited a mix of units,
and once I had three of a type appear in the list, I cast three GoRs with
three different mages.

The result? No, not three commanders. Not one either. Two. *shrug*
