Sequence contains more than one matching element

I am getting this error from TeamCity running "GitVersion 3.0.0-beta0002":

I created branch, committed and pushed, created a pull request against a branch and then committed an additional change to that branch.

GitVersion parses the original commit (2.0.1-abc.1+1), the first PR (2.0.1-PullRequest.5+2) and the second commit (2.0.1-abc.1+2) but throws the above exception when parsing the PR. There are 3 tags against the repo.

Are you able to check if master has the same issue? There are a few fixes to still go in around this particular class, but there have been a few already

[richardwadsworth]

master builds without the same issue.

[JakeGinnivan]

Great. I am working on getting beta3 out over the weekend. Will let you know once out

[richardwadsworth]

perfect thanks. Interestingly, I've just forced the build on that same PR (after making some other unrelated commits and merges) and it's built ok with a build number of 2.0.2-PullRequest.5+3. Note the patch has incremented.

[JakeGinnivan]

I think that is the same as this: #415

[JakeGinnivan]

Pretty sure this is fixed

In master that is, next release should not have the PR version issue
