---[X] Drop 3x Manufactories, Captive Holding Cells. Build The Oubliette (Or, the Bongo Containment Zone), 4 Slots, Up to 8,100 BP for 540/540 HP. Move the Scrapcode Generator there after Further Scrapcode Research is complete.
Why are you dropping manufactories to the point that we need multiple actions to build a ground manufactory? Alectai's plan did that, but they also had a research to increase the BP generated by the ship's manufactory, although looking at it now it would still have been less than enough to build a manufactory unless we had at least a Good Success, then it was changed to another research with the same cost which would double the BP from our ships, then i have no idea what happened, i was sleeping.
If you drop a shuttle and 200 BP from the repair bay, you free the same space than by removing 3 manufactories, and we can build 200 BP fast enough that those 200 usable only for repair won't have a noticeable effect in most cases.
