Patches F and G disables research.
I just made a new clean isntall of 0.34. First the main mod, then the media pack and then the patch F. Started a game with Kuriotates and the entire tech tree (aside from agriculture they start with) was all red. I was not able to choose a tech to research.
So I thought perhaps it was an issue with the patch F, which worked for me before. I deleted the mod folder, downloaded patch G and made a second clean install. Started another Kuriotate game and what do I get? Red tech tree, you guessed it I'm sure.
Out of curiosity I deleted the mod folder again and then installed only the main mod and the media pack. Just to see if they are corrupted. (I'd rather not dl them again.) Yet another Kuriotate game and yes, this time I could research. When I applied patch G again, the mod broke. What a surprise.
Finally I checked if this was a problem specific to Kuriotates but no. Capria of Bannor cannot research either.
