"None" option in dropdown for enum types marked with [Flags] does not work

[Tarocco]

For flag enum fields, Odin will create an improved dropdown menu for the inspector.

The "All" option is working as a toggle for all of the flags, and the "None" option raises this exception:

InvalidCastException: Cannot cast from source type to destination type.

Thanks for reporting this issue. I just tried to replicate this with no luck - could you paste your enum definition in here?

After some further testing, I did manage to replicate this. Enums for all types of both negative and positive values now work. This fix will make it into the next patch.
