PvK, please either move Organic generation into a separate group or at least put them below Organic farms in facility.txt.
I think 99.9% people play SE IV with "show only latest" on in constraction window. As it is now, organig generation facilities are invisible, being override by organic farms. To build them, I must to uncheck "latest only", put them in queue and swith "latest only" back. Extremely inconvinient.

Even worse, every time I research, for example, space yards II and press "upgrade facilities", SE IV tries to replace organig generation V with organic farms III
I still do not like the lack of research requirements for Major city. The fact that several cultural facilities are available from start gives me headache: I must to switch off and switch on "onlly latest" if I want to build cheap town and constantly monitor construction every time I hit "upgrade facilities".
Worst of all, it makes impossible to programm AI to build cheap cultural facilities first and upgrade them later (it always build th latest available). PVK, please assign some research requirements to low-level facilities. IMHO, it will make this mod even more flexible and interesting.
I am rather confused with "unresearcheable tech."
It is only to make older save games compatible with 2.2, right ? Can I delete all these dummy facilities if I want to start a new game ?
I think there is a type in "researcheable" Archology (one in the bottom of the list). It is assign to a wrong facility group than city-megapolice-metropolice facilities. I am pretty sure it is a type, but please check it.
