Adsense Has A Mind Of It’s Own! – Elf Knows It [ARCHIVED]

For the past 2 days Adsense has decided to take on a mind of it’s own, using what ever design it feels fit on my site!. Adding a black border randomly around my ad’s.

Screenshot I snapped of one today:

As you can see with the ad’s I have no border set in the style for them.

Has anyone else noticed this? Bug with Adsense maybe?
