Great, let's come to a compromise, what would be fine is the Era version just before the main scripts were rewritten. My Era 3.0 has bugs with displaying wog options then loading dat files crashes the game, I didn't test all Era version between 3.0 and 3.9. I checked Igrik WoG scripts mod and it looks fine, not updated recently.

Since the launcher version breaks compatibility with previous mods using wog scripts, would it be possible to create a package like Era 3.0 but 100% functional? With the necessary plugins like fix game issues so everything is fine.
