[LH2909] Synopsis not included in .csv export of outliner

Version: 2.9.0.10 Beta (331056) 64-bit - 28 Sep 2018 on Windows 10.

The synopsis isn’t appearing in the .csv export of the outliner contents, even when I open the file in Notepad. Am I missing something? I can’t find a workaround and I use this function heavily.

You are not missing anything. This is a known bug that we are hoping to have fixed for the next beta version.
