If it is within the Towns border you can now just click and build. Costs are the same and I assume Turns required seem to be the same.
It does seem that the Techs are still in the Tree but I guess that is so if you need to send out a Pioneer right away, you will have the required research tech available. Not really an issue given a SoV always starts near a Farm-able tile...
Even though Mines, Farms and other stuff do now seem redundant as far as Teching to them, or getting beyond them, though.
Surely they will fix the "not showing up" in the Build queue for 1.0 and perhaps, once one selects a Farm tile, and builds on it, that tech will be pulled from the Tech Tree such that I only see the next tier of Techs under that one. Same would apply for all in border click and build resources.
