Enigmatic Engeneering effect gone after delta special project?
I've noticed that after concluding the necessary project for delta buildings and stuff that red fallen builidng techs no longer appear in science roster (like Aspis Bastion or Justice complex). Which I know is outperformed by other modded techs but it still kinda bums me out.

Is it a bug? Design feature? Or something else entirely?
