On the 15th of May I added version control to a project I've been working on in Xamarin Studio and made an initial commit, which I pushed to bitbucket. All was fine, and the code was viewable from bitbucket.
Then before starting work on some improvements of the app, I made a new branch and started working on it. Today I pressed "Version Control --> Update Solution" and "Version Control --> Merge Changes" which resulted in all the code I had written since the initial commit on the 15th of May being deleted. The logs both on my computer and on bitbucket shows no entries since the 15th (initial commit). What might have caused this, and do I stand any chance at getting the files back?
