[CONQUEST EASY] - Do i need to win 10 or 20 battles with at least 3 rebels?

I want to report too, but you were faster :)
I hope we will have a real answer :)

20
The text describing the feat is just text seemingly with many typos this time.
You could actually with a text editor make them say anything.
The numbers on the right are the actual counters.

Of course they could "fix" it all

its likely meant to be 20 but they put the wrong amount on the description, similar (but inversed) to what they did on hard mode with ewoks needing 20 wins vs the 40 the description says.
