A repo that I have successfully used as a submodule on another project now fails when I try to attach it. Everything is bitbucket repos, so authentication for a submodule within a repo that is from the same bitbucket account doesn't make sense. I just checked out that repo a moment before I tried to add the submodule.

Also, the error mentions looking for files within the local folder of what appears to be Manjunath Basaralu Srinivasa's computer.
