| Dynamic Dispatch method overrides do not save updates
In specific situations, changes made to method overrides will not save. Reopening the VI after saving changes will show the previous code. This prevents users from updating Dynamic Dispatch VIs for child classes.

| LabVIEW can crash or display incorrect text characters when "Use Unicode UTF-8" option enabled in Windows On systems that have the Windows option "Beta: Use Unicode UTF-8 for worldwide language support" enabled in Region settings, LabVIEW can crash or display garbled text in some languages. To find the Region settings go to Control Panel > Region > Administrative > Change system locale...
This option causes the system default code page to be UTF-8, which LabVIEW does not support.
R&D made changes in the LabVIEW 2020 f1 patch to prevent the crash, but some text will still display incorrectly in some languages.
Workaround: Disable the "Beta: Use Unicode UTF-8 for worldwide language support" option in Windows.
