inconsistent 404s on downloads (tags not working)

i'm getting 404s when trying to download tags from a /downloads page. i'm able to download branches, but not tags.

test page/repo:

https://bitbucket.org/stephenmathieson/testything/downloads

working (branch) link: https://bitbucket.org/stephenmathieson/testything/get/master.tar.gz

not working (tag) links:

• https://bitbucket.org/stephenmathieson/testything/get/0.0.3.tar.gz
• https://bitbucket.org/stephenmathieson/testything/get/0.0.2.tar.gz
• https://bitbucket.org/stephenmathieson/testything/get/0.0.0.tar.gz

oddly enough, this was working a few hours ago.
