I wanted to add an accessory to a character, Steven S. This is after I had added a bunch of animations to him, animations I didn't want to re-create.

After selecting him and clicking on the Composer button, CTA3 popped up a warning: "Detected new motion in character. To start character bone edition, you will need to Remove Object Animation in order to unlock bone edit function. Do you wish to edit other features inside Character Composer?"

With a question like that, I'd expect buttons for "Yes [meaning, Yes, I want to edit features other than bones]" and "No." Instead, I get "Continue" and "Cancel." 
Neither of those current button texts make any sense in this context. I suggest at least changing "Continue" to "Yes."
