Dont tag like that the gold might result in that the status is not ok when run atuomatic.
When it was my script i removed the GC code from the tag
It can be used http://project-gc.com/Challenges//19597
You could add the link as a comment from the bronze tag.
Is suspect the tag with the gc code will be auto disables when the cache is missing the required challenge in the title when the challenge was published
As it is not it is a mystery cache with a ALR(additional login requirement) that are not allowed and can be ignored.
The CO should change the name of the challenge
