When creating a review and adding a branch, Crucible will sometimes add files outside said branch, i.e. from an other branch. I have several reproducable examples of completely different FishEye repositories.
Why would Crucible do that in the first place?
How can I prevent Crucible from doing so?
Would you be able to share those reproducible examples with us, so we can inspect in detail? Raise a bug in https://jira.atlassian.com/browse/CRUC ideally, please.
I have never seen such behaviour yet. Perhaps you want to view Review History (from the Tools cog) to double check the other files were not added by other review participants?
