glitch or intentional: If you cast glamour from a item, that item will become bind

[Xellos2099]

I am not sure if it is intentional or not, yesterday i manage to craft a cashmere robe of casting hq and put it on market ward. Today I was thinking before i sell it i might as well glamour it to my sorceror coat. It glamour alright but it won;t let me put i on market board. There is zero warning saying if it is being glamour, it become bind to you.
