I think I've found another small problem.
Later in the game, uranium is revealed (I think by phisics, right?).
Then I build mines at the uranium spots (I even had a city where a uranium resource appeared). The production and gold bonuses are properly given... But I then tried to upgrade my frigates to destroyers... And it keeps telling me I need either uranium or oil. I went inside the cities and none of them had uranium displayed as a present resource (there at the upper right corner of the city interface). A little later, with combustion, I built some wells and was able to upgrade the frigates, now using oil.
I played some more turns, got further in the tech tree, but uranium still doesn't show up as a present resource in any of my cities... So I guess something is wrong.
I'm using all modules released (at the begining of this post), except for the interface 1 (can't download it, don't know why), resources 3 (because of the problem mentioned in the previous posts) and civs 3 (the same reason)
I don't know how to isolate this, because if I uninstall modules, my save game won't load (tried before in another game), and this is far too advanced to keep playing a game after installing each module (the way I isolated the resource 3 problem...). So I guess it's up to you guys to find out what is wrong...
I hope this helps...
