To mod a late-game feature, is the only current way to do this to play an entire new campaign from the Neolithic age?

When trying to load a save with a new mod activated (something I was working on), I got an "Invalid Save" error and there was no way to force load the save file. I think it wanted me to start a new game.. This might be covered in known issues:

• Modded savegames become unusable if the mod is updated. There is currently no way to opt out of automatic mod updates

This mod helped me for testing : choose starting era.

This is great! Thanks for the tip.

Also I saw the "Remove the Humankind FOW" mod on that site that will be really useful for mods and map creation.

That was very easy to install and works great. Thanks for the input!
