I'd like to change the Issues Types Scheme of several projects. I order to standardize the issue type scheme, I use the Default Issue Type Scheme, when I have to Archive the project. As the project is link with the default issue type scheme, I can delete the project issue type scheme.
Because there are all the issue types in the default issue type scheme, my issues do not have to be deleted. However, when I restore the project, I lost all the issues.
Could you please tell me why the issues are gone?
