Hey Game Programmer,
When opening the project in a new version, did you use the ‘Open a Copy’ option or the ‘Convert-In-Place’ option?
Since there are a significant amount of fixes and features implemented between major release builds, which can include any number of changes, we suggest using the open a copy option. This will help guarantee your original project is not corrupt, in case situations like what you are experiencing occur.
Would you mind providing me with some screenshots of you scene and light settings so I can have a visual representation of the issue?
Thank you,
