Seems like they changed the site and div[id=comic-wrap] is not a thing anymore, i think i might be able to fix that by using the div tag with id=comic

I was able to fix the issue regarding the feed, but i noticed another issue, this bridge is using feedburner to retrive the comic list, and it appears that since the website was updated on 22/Dec feedburner stopped updating articles.
I think there is no rss option in the new site and another solution is required.

Solved with the merge #2417 , this was a bridge-braking issue.
