Building requirements for advancing

[Pancrol]

I was just watching a Forest nothing game and noticed that TaToH rebuilt a lumber camp and a mill before advancing:

DauT vs TaToH playing FOREST NOTHING? what is this!!!!!

I can not be certain about the lumber camp but the mill for sure had been built before as he already has farms.

It's not the first time that I see players on nothing maps build the required buildings again just so they can advance and I wanted to make it clear that the game doesn't check for the buildings to be present, just that you built it at some point.

Most buildings (at least the pre-requisite ones) trigger a technology upon being built. This technology has no effect but, once researched, stays researched for the rest of the game. In order to research the ages, you need to already have researched two of these technologies that associated with buildings. What the game looks for is not the building, it's the technology associated with it. Therefore, it does not matter if the building is not actually present.

Oh, you need 2 buildings from the current age at the same time to unlock the next age. If you build a Mill, delete it, then build a Lumbercamp, the Feudal Age doesn't unlock. It's always been like that as far as I'm aware, even in Aoe1.

But you don't necessarily need 2 buildings at the time you are clicking up, right?

As in if you made siege workshop and monastery, then you delete the monastery - can you still click up? I always thought the answer is yes which is what Pancrol is also arguing.

Yes, but that was not what happened in the video he linked, and I assume not what he was asking.
Daut built a market, then deleted it without building the blacksmith at the same time, so when it came time to click up he had to build the market again along with a blacksmith so that both were standing at the same time.

Same thing with TaToH, he had one of each building at different times, not at the same time.

Robo is actually right, I tested yesterday by building two buildings, deleting, and checking if the age was available. Indeed, if I build and delete one and do the same for another building, the age is not available.

This totally perplexes me, as I thought I understood the way units trigger technologies and I've been using it a lot to queue techs in the Community Patch. There's probably some inner working I'm not aware of.

Anyway, thanks for clarifying the detail I was missing.
