Commit and code missing from master branch after merge

[Kobi Rosenstein]

I worked on a feature branch, and merged it via a PR. I think I used the "Squash" option, because the PR shows one commit message, which is made up of all the commit messages of the commits on feature branch. However the project and repo settings both only have "merge --no-ff " merge strategy checked, so I don't know how I could have even squashed.

In any case, the PR says merged, but none of the commits exist in the commit history, and the code changes do not exist on the target branch (or any other branch for that matter).

I read this post:

https://confluence.atlassian.com/bitbucketserverkb/commits-missing-from-pull-request-merge-on-target-branch-825786786.html

Which explains why i wouldn't see the feature branch commits, but I do not see the squash commit either, and I would still expect to see the code changes.

Force push is disabled at both the project and repo level, so it could not be that either.

How can i find where the code is at the moment, and how can I make sure this does not happen again, and how do I check that it has not happened in other branches as well?

Thanks.
