There is a bug that, if you are doing a chat wiht live search active, and in each message you provide a new link to search, on the third one it cannot crawl the web page.
I.e.:-
User: Asks question with link.
Merlin: Reads link and responds.
User: Asks a second question with a new link.
Merlin: Reads link and responds.
User: Asks a third question with a new link.
Merlin: Says it cannot read anything on the link.
