The addon is nonfunctional in the pre-patch and throwing up a lot of LUA errors. I'm not sure which is the most important, but here are the most common:

15x Interface/AddOns/BagSync/wireframe/tooltip.lua:316: attempt to index field 'options' (a nil value)

It looks like they just disabled and reworked a lot of their code to break addons. Why am I not surprised. They do this every patch and every expansion. I'll take a look at it, but without an active account this will be interesting.

If there's anything I can do to help beyond posting LUA errors let me know. Your addon is a lifesaver.
