I mean that the entire folder in the library structure is part of the 'list schemes' (basically, the Calculate Menu functions). They are not themselves a list scheme, but only via list schemes can you report any of the information you are generating by doing the linking.
Yes, I did not mean comparable libraries (default) - I meant exact the same (and no other) libraries. Since you have tried that, then the only other options (I think?) are (a) that you have some add-ons in 13 that are not in 14 - temporarily either remove all 3rd party add-ons, or make sure that you have the exact same ones in each, or (b) GS changed something in 14, which is what you asked at the very beginning...
Cheers,
