I have enabled the option to automatically push new commits to the remote repositories.

When I have no network connectivity and trigger a commit, forgetting to uncheck the "push to remote" option, I get an error message that the push failed. At the same time, my working directory is clean, but I cannot see the commit I just triggered in the list.

After restarting SourceTree, the commit appears in the list.

This behavior can be reproduced quite simply: disconnect your machine from the network, and trigger a commit with "push to remote" enabled.

Best regards!
