@Thunderbrd it appears recosting was bit incosistent - in first 3 columns I managed to find several recosting errors, that is building was recosted after least expensive tech not most expensive tech.
Also i'm checking building prereqs of buildings.
That is if prereq of X doesn't appear later than X.
I already made sure, that resource prereq doesn't appear later than building.
Something could slip due to recosting errors though.
All modifiers are set to 100 and I have recosting guide in excel, so its easy to check.
There is weird issue with Jade Carvers:
They are unlocked at Carving (X8), but they need building unlocked at Barter (X12, Jade Merchant local) or Trade (X24, Jade Importer), that is much later.
Cultural Jade Carvers have additional proxy tech prereqs:
Liangzhu - Celebration (X17)
Olmec - Megalith Construction (X16)
Shang - Sacrifice Cult (X23)
You need 9 techs from staring point to reach Carving, and you need 42 techs to reach Barter from staring point.
From description of Jade Merchant/Importer it sounds like it should be like this:
At Carving you have Jade Carver, that needs Jade in city vicinity.
At Barter/Trade you can build Jade Traders, that you can build anywhere as long as one of cities has Jade Carver.

Here seems like Gem Cutter should require Jewelry Store not vice wersa.
Ger requires Equine Domestication (X16)/Portable Shelters (X12) and Stable, but Stable is now at Animal Riding.
Bumping Ger prereq to Animal Riding/Portable Shelters.
Ger is religious building, that needs Tengrism, and this religion with tech of same name needs Animal Riding.

Bamboo Bridge (X13 - Carpentry) is two columns ahead of Stone Bridge (X11 - Stone Bridge), but Stone Bridge replaces Bamboo Bridge....
Next one - Brick Bridge is at Masonry (X24)
This means I need to look for better place for it.
Megalith Construction (X16) looks good enough - this is effectively more advanced version of Stone Building tech.
Stone Bridge will now require Megalith Construction.
Flocks of.... Effect are limited to Earth (Poultry Domestication)

Whale Oil resource will have unchanged tech reveal.

Pleistocene Park now requires Mainstream Cloning.
Ground Scrubbers now reduce air and water pollution by 50 instead of increasing air pollution by 100 at cost of decreased water pollution (-200).
