Version: 1.10.11

Steps to reproduce:

1. Create fresh profile.
2. Enable the Bar State for Shift on Action Bar 1.
3. Drag Spell from spellbook to slot 1.
4. Press and release Shift.

Expected result: Spell casts.
Actual result: Spell does not cast.

Spell will cast fine right up until you change the state of the bar, then it reverts to whatever it was before the drag-n-drop, this happens even when moving already bound spells/macros.
It's visually still on the bar, and looking at the individual button macro says it's correct, but it won't persist through a state change until you modify something in the macro editor and re-save.
It looks like it's not saving the macros after a drag-and-drop event happens.
I believe this is the same issue as #199
EDIT:
Some updated info:
Doing a /reload fixes it, making the actions match the visuals again, but having to do that after shuffling buttons around every time is a pain.
