Hey Seasnake!
Maybe you can get a chance to check this out:
The ressourse "Titanium": After discovering it and resarching all the required techs in the late game I have it in my territory, have a mine and railroad built on the correct square, and yet I do not get the ressource. And yes, the symbl for the ressource shows up pink - maybe you have a fix for this?
And again: Great mod!
