rake aborted

[Mxke]

While running through my author list, I consistently receive an abort message, which also comes up during the full replace function. No PMCIDs are being pulled or into my Mendeley library. Any insight would be appreciated. Here's the error message (starting with the last author in the list):

Fix author "Todd A Florin" --> "Todd A Florin"
