Just purchased and downloaded the game, but I've immediately run into a problem. I've googled and searched the forum for this issue but couldn't find anything so I figured I'd post here and someone can show me what I'm missing. When I go into the research menu, I don't see the Land, Naval, and Air doctrine tabs at all. This issue remains whether I run vanilla or the expansions I've purchased (all except for the latest one). Does anyone know what is going on?
