Describe the bug
A clear and concise description of what the bug is.

I have multiple gear sets for a druid. I generally have a cat form, bear form and caster(boomkin) form set.
Caster is the default when i am out of form, in travel or flight form.
When i switch from caster form to cat or bear form, the gear does not change. I realize in combat that this is normal but out of combat my gear used to change with form changes. Now it does not.
I can manually change the gear.

i did notice prior to this happening I was getting an error that claimed I could not put my off hand item in my bags even though i had bag space.
I no longer get this error but as above my gear wont switch.

To include the lua error, paste the error in between two sets of three backticks:

I don't have a druid in TBC. I'll look into it, but I don't know how far I can get.

If you're comfortable with event tracing, I can suggest some events to look for to see if TBC changed them.
