Building upgrade chains big bug

[Nimek]

This issue was discused many times but nobody fix that.

So my big kind request. Please do somy python changes in upgradable buildings code that way that upgraded building act as old one if old one is required to build something else.

Example
I wanted to build Library of Nineweh so i need 4 Tablets makers (tablets maker rewuire storage pit) i built 3 of them but now i discovered potery (storage pit obsolete) so i am unable to build tablet maker in my 4th city because it dont have storage pit.

Please dont tell me that i can auobuild barte/trading post because this is not solution for this problem. It ocurs many times in many games in many threads in this forum.

Just fix it please

Tablets Makers require Storage Pit OR Barter Post OR Trading Post. At what point is the Storage Pit replaced but not with the Barter Post OR Trading Post? The Granary and Warehouse replace the Storage Pit but you should have the Barter Post already Auto-Built before they become available. I have tried to fix this problem a number of times, but I don't see when there is a situation not a Barter Post. Especially not that the Barter Post is both Auto-Build and doesn't require Barter civic anymore.

Also the Library of Nineweh should be obsoleting at the same time as the Tablet Maker.

Which is "Paper" tech.

Checked - it is. That is one of Orion Veteran's wonders.

edit so can tablet makers be built right up until you have paper? IE are its prerequisite buildings available right up until then?

Should be. The Trading Post doesn't get replaced with the Shopping District until Consumerism (x66), which comes long after Paper (x38).

And Common Clay, Fine Clay and Stone never go obsolete.
