Greetings!
Just wanted to drop in and say how much I am loving this mod. Particularly the terraforming and planting trees which allows me to, finally, have some way to combat that damned Global Warming.
I have attempted to search out the answer to this question myself but have come up empty: Is it intended that one lose the ability to build advanced MBTs and mobile artillery after researching certain techs?
I ask as after researching fusion I lost tanks entirely except for Mammoths (and Behemoths later on). Also after researching cold fusion I lost Mobile Artillery. I am currently left with only mechanized infantry, standard infantry units and all the national units thus far unlocked. Compared to the wars I've fought thus far that doesn't seem like a lot of units to defend my rather extensive empire with.
Also, as another poster mentioned, I too am having the odd occurence of even naval prototypes appearing in my landlocked capital.
All in all, I am having a blast with this mod. Thank you much!
