i just played around with the build_enemy_base command and noticed, that you need another base in 'range' for it to work and that it will only tell existing biters to move to the new location and form a base.
I think it would be nice to have an option to directly spawn a base of size equivalent to xy biters running there.
If that's not possible, a workaround would be to spawn the biters that should be send near the area if no biters were found that could be send to the new location.
I think that would make this function a bit more intuitive because at the moment, you can't tell if it worked and you can't "force" it to work. In my opinion this function isn't useable in mods because it's to unreliable so one has to 'reimplement the wheel'.
Thanks for reading
