Source browser not displaying latest commits.
Files exist and can be accessed from commit log only.
I may experience the same issue. In my case it is a branch which is "stuck" in the past.
When I attempt to access the branch through the "Source" menu and choose the branch name on the dropdown, I am directed to a URL on this form: https://bitbucket.org/USER/REPO/src/BRANCH/ which displays one of the first commits ever made on that branch. One interesting observation though: The "Last Commit" and "Message" columns actually show the correct information taken from the head of the branch for each file.
