When I went to the new Market page, I noticed some of the dropdowns are different. Instead of Community containing the Community Guidelines, it's replaced with the Character Copy. The Forums link is there, but the address is messed up (appears to be missing a /) so the link doesn't work. The Store dropdown only has three options, as opposed to the six available from most other portions of the site (or at least the forums).
I haven't seen any other errors (the other dropdowns appear to have the same links at least) but I haven't tested any of the others to see if any are broken.
