Abandoned transaction found - run hg recover!

Hi. I'm using TeamCity on a build server, and I keep getting an error about being unable to pull changes from BitBucket, so I'm currently unable to build and deploy. This is in the logs: "abandoned transaction found - run hg recover!". For what it's worth, I did try to do a pretty big commit yesterday, if that makes any difference.

Is there any way for me to do this in the admin interface, or does someone else have to do it?

This is my repository: https://bitbucket.org/rjwiffen/accountsflow
