This is a simple refresh of the UI issue.
If I add ranks to Speak Languages - I can add/remove the languages and they appear in the skills version. However, switching to the Summary Tab, the skills don't appear there. If I click the + button for the skills based, they are present, and closing the box they'll populate the languages box then.
Language list now listens for changes to the character's languages.
Some manual refreshes still occur at points where the list of possible languages is likely to be changed.
