Thanks for the file example, I copied over the techs to @Civilize2 near the bottom of the rules but the problems persist. The file example you posted doesn't utilize the full 252 techs do you have an example that does?@Civilize2 is already in the rules file - you don't need to create a new one and if you do who knows what may happen.
Here's a rules file with the extra techs that works that you can compare against your own to see what issues you may have. Sorry I'm at work. If you can't figure it out, if you post yours I can take a look later.
Here's my rule file from the Midgard scenario which I'm currently working on. I've removed the tech requirements for several techs as nothing after 220 seems to work correctly.
