Ok, I found 2 mods that appear to have been causing issues. I upgraded to the newest version and had only the buildings and a couple other mods enabled. It appears the mods GameOptions (enables all hidden options) and Beyond the Future aren't compatible with CCTP. Is it possible for you to take some elements of Beyond the Future to add into CCTP? I know I would at least like to get the units from the mod to use. I also noticed when I checked IGE that you've added a few new eras which is pretty awesome and probably explains why BTF doesn't work. Again, would like to see the units added from that mod though. I'm still being cautious as to what mods I can use. At least I can use my modded civ and IGE, which is a start. I'm going to try a couple other mods that might be incompatible. I wish this game had a load order like there is in other games like Fall Out and Elder Scrolls. There wouldn't be as many incompatibilities then I would think. This mod would simply overwrite the incompatibilities.
