I figure here is more appropriate for this than Mantis since as far as I know I'm the only one with this problem. I've got the 'launch rock' spell in my inventory, but the game insists that I don't know it on this continent. This is a game that I started with the first open beta, so no doubt I'm being silly by trying to keep it working. I've attached the world.dat and region.dat and the folder for just the home settlement. If I recall correctly, that's all you need to look at it, yes?
