I just discovered this and it made me want to cry.
I used the assign_variable to assign a current_blog variable to my templates. When I created new weblogs and duplicated those templates it had gone and replaced all the occurances of weblog=”{current_blog}” with weblog=blog_shortname.
Which was unexpected and made this use of the assign variable really frustrating. I therefore hereby request a feature to not update the weblog= fields when duplicating templates for a new weblog.
Please. =)
