What technology do I need to build fortresses??

[unmerged(502)]

It seems like I cannot update the defense infrastructure of my provinces even to level 1 (redoubt) - do I need to have a specific technology to do that? I am playing as Ecudor and I believe it should have the technology to build at least a weak fortress in 1836. Also, when I try to click on the defense update button in the province screen it wouldn't say me what I need to build a fortress - it justs says "you lack the following" and then it is blank (it used to have resources listed, but now when I have everything required it just says I lack "nothing"). Is it a bug of some sorts?

so, does anyone know what I am doing wrong?

Yeah it does the same thing for me. We probably are lacking something but the game is unable to tell us what. I had the tech to build a level 3 fortress but it still would not let me build level 1

an annoying bug,
make sure you have more goods than needed and it should work.
I think that an extra 50% should be enough

The same thing happened to me except I could build fortresses at first, then for some reason I just couldn't anymore. I have the tech and more than enough resources.

Theres a bug which prevents level 4 / 5 forts from being built sometimes.

Being able to build different fort levels comes from inventions rather than tech.
To see which ones are required take a look at my Army tech tree FAQ in the FAQ forum.

My problem is I can't build anymore LEVEL 1 fortressess even though i already built some, and I have more than enough resourses, plus i got the invention for level 2 fortressess but can't build any.

it has to do w/ explosives, i think... Try to build up a huge amount of explosives (or cheat), and then come back and see if you can build the fort.

If you not lacking the resources or Money, are you upgrading your Railroads in those provinces? If so you can only do one upgrade at a time.

I had this too.

Would fiddle with the necessary resources in the trade menu, lumber/cement/explosives(usually just explosives), and it would usually work.

Edit: By "fiddle", I mean add more in number then I need, or buy more(even if I produce enough).

There is a known bug preventing fortress upgrade in certain situations.

Searching through the techs and inventions, I can only find stuff that allows you to build level 2 or higher. Therefore I guess that you should be able to build level 1 forts no matter how backward and medieval you rcountry is.
