In the shadows/riftborn Custom faction bug?

So have some problems with the custom faction combination, of the gameplay affinity called in the shadows and the visual affinity Riftborn, when i go ingame with this combo, and i hack a system, and i have got a base, i cant rememer the name but the thing the umbral chior can place instead of a base, and i have max pop cap in my system, and i want my home system to make population on the new base, then i press the send new pop to the other base, i toggle that, and then i place a riftborn pop in the queue to be made, then i end the turn, and it has been made, but it has not been sent to the other base. is there a fix to this, i really like to play that custom faction.
