I select a bunch of new files to commit, then try to commit. I get the popup saying "Checking submodules" for less then a second, then it closes, and comes back to the main UI with nothing checked in. I can check in files to the repository by hand from the terminal, so the repository isn't the issue. This is on Windows 10 with a repository on a Windows network share. SourceTree 3.1.2, although this has happened to me a few times on earlier versions of 3. Previously, checking in a commit by hand shook it loose...this time, no dice. Also, I have tried it both with the "Push changed immediately" checked and not. I have tried rebooting.
