I am sure I am missing something obvious, but as a synthetic, how do I build new legions? I see that the 2.2 bug is in play so I get some each time I conquer a planet which is great, but need to build up to take an 8 legion defended homeworld which means I either burn civilians or else I figure out the required tech to build legions, but simple can't figure out which tech that is.
Thanks for the help.
