I'm trying to use the Alpha Emissary to colonize in my own space, and for some reason, it's not working. I can't use the Emissary W beam (the collosus weapon) cause somehow a normal world isn't an applicable target, and even a baren world isn't acceptable, despite that being in the system action menu.
and when I check the precursor archive for details, it says to orbit first, but I see no option for it to ever enter orbit, it just flies to the destination.

What am I missing? Or is this a bug? Oh, and this is entirely me trying to use it as a colonizer, not an invasion force.
