Hmmmm... Thanks for posting Tallon.
After your comment about it being your host, I thought about it for a minute and just removed the .css block from my robots.txt... Couldn't imagine why they would need the layout of my site or the .js files so I've been blocking them for at least 5 years without an issue, just because I don't like giving them any more than I have to and it saves a bit on bandwidth. Until now they haven't really had any good reason I can think of to need to use either, but maybe they couldn't get a decent screen shot or figure out where things went because it was blocked? IDK, but it makes a bit of sense, so I'll let 'em in and see if they can do a better job with the image in the SERPs.
