I solved the problem with this game.

Crystal Tools was used to build 1.0 (and was one of the reasons for its downfall). The developers use the Luminous Engine for most of FFXIV now—however, there’s likely still 1.0 spaghetti code floating around, and I really wouldn’t be surprised if its continued existence is why some things aren’t implemented; or why other things are implemented, but operate in an extremely cumbersome way.

Nearly all the old code was scrapped. IIRC it was only some item and character database stuff that made the transition, primarily because 1.0 characters had to be able to be imported into 2.0.

Which makes sense when you think about the type of things they have issues implementing.
