The command "Save a copy of this project" leads to data loss if a new project name over 240 characters is entered.
After clicking "Save a copy of this project" and entering a long project name, a warning message appears that the specified path, file name, or both are too long. If the user clicks OK, the window closes and the Projects folder is deleted. Although it's possible to restore projects from a backup copy, linked PDF files cannot be restored -- not even from the Windows Recycle Bin. Although the error has only been reported once so far, we wanted to warn all of our Citavi users.
In several days we will be releasing a new version that includes a fix for this error.
