I am having errors loading core overmap terrain and specials

Version is windows 64 9397. I am loading several mods that add locations.

These mods need to be updated. Mentioned locations were made rotatable in vanilla.

Ok so rather than providing the error saying there are too many mandatory specials it does this instead?

Yes, it is not related to a number of specials, so no error about that.
