So I was playing around with mods, doing up some new races, and now I can’t switch races anymore!
Despite copying my old default data directory over the modified one, so I should be back to standard, and despite the fact that a gold panel for ‘expert’ appears, none of the races can be switched to.
I did create and delete a scenario file for scenario 12, if that has any bearing on this. - Actually it does. It made a new entry in sc.dat which I’ve had to delete!
