I've been following this thread because I was having similar problems and hoped a solution would be offered. I did the following: I spent several hours deleting and reinstalling my most recent installations, but that didn't work. Finally, I was forced to delete my current MODs folder and reinstall the back-up which was functioning correctly. From that point, on a one-by-one basis, all the folders I suspected. The two major suspects were Forgotten Countries v1.01 and the most recent Zuti_Slovenia update. I reinstalled all my missing folders, but the Zuti_Slovenia update, successfully, so that must have been the problem.
That's the solution that what worked for me . I hope it helps you.
