B113 Snapshot including custom direct selects not saved in esf2 format

What specific Direct Select information are you seeing missing from snapshots? Mapping and paging seems to be working fine for me going between 3.1.1.113 and 2.9.1.17.

in 3.1.1 I created a custom direct select with 9 Focus Pallets, 4 Presents and 5 Effects in a particular arrangement and saved the show in esf3 and esf2 formats. Opening the esf2 in 2.9, the frame arrangement is correct but there are no defined buttons in the direct select tab.

Custom Direct Selects changed in 3.1, so the button mapping is now within a target, rather than stored as part of a Snapshot directly. As such there wouldn't be a way for CDS mapping to carry backwards from 3.1.
