Could you please post the results of git log --graph --abbrev-commit --decorate --date=relative --all --max-count=100

Hopefully we should be able to see enough of the graph to figure what is going on in 100 commits. Somehow the feature branch has been tracked multiple times, I want to try and create a reproduction test based off your commit graph

That looks incomplete, it is only showing 3 commits. Can you put it in a gist as well? (https://gist.github.com/)

[JakeGinnivan]

Also if you surround it with three backticks it will not try and format it. Or indent it by 4 spaces in a text editor before pasting into gist

[hotants]

Please find it from https://gist.github.com/anonymous/0891af15b64f533d37bd
Thanks

The NullReferenceException is coming from https://github.com/ParticularLabs/GitVersion/blob/master/GitVersionCore/BranchConfigurationCalculator.cs#L120

var hasDevelop = repository.FindBranch("develop") != null; // Not null because origin/develop exists
...
... repository.Branches[branchName] /// null because 'develop' doesn't exist

[JakeGinnivan]

@yannisgu nice work.. That does look like the issue!

[JakeGinnivan]

@hotants thanks for reporting, should be released soon!
