Hey great mod, not sure if it's possible but I think I found a conflict with the mod RHQ Artificially Intelligent AI Mod 2.02 /rhq-artificially-intelligent-ai-mod.31881/
When both are installed, starting a single player match will give me a 'content confirmation validation failed' error and send me back to the main menu.
I already messaged the other mod author but figured I'd put it on your radar too :)
1) Go into RHQ's files -> modules -> vict. You'll need to make a small change in the Ant, Exploration, and Modern files there.
2) Find the "Temp Civ Preferences" section in each file. In the version I have they are near the bottom.
3) Then, either delete the sections or surround them with /* (before the first line) and */ (after the last line).
I did this and the game was able to start. This general procedure (find wherever a mod updates the tables I mentioned and delete them) should work for any other incompatibilities that pop up.
Thank you again for using my mod!
