Symptoms
- There is a loss of information when trying to merge scenes and prefabs into a version control system.
- I receive a notification that there is a merge conflict.
Cause
This can occur if you are working in a project with several people and two or more persons are modifying the same scene/prefab.
Resolution
In Unity 5, a smart merge tool was added called YAML merge tool. Please review the documentation for information and guidance.
