Template:GlobalProblems/sandbox/doc

This should display:

This should not:

Calling the template twice on one page (like this one) should also add it to Category:Pages calling GlobalProblems template improperly.

Because this template always has to call GlobalProblems/Virtual Console and display bugs from there, any page that calls GlobalProblems as  (as in just one page, Virtual Console) causes the template to call GlobalProblems/Virtual Console twice. This is bad behavior but it's harmless, and trying to avoid it would make it slower for every other page to benefit that one single page. The Virtual Console page's GlobalProblems call also introduces the possibility of accidentally displaying issues from GlobalProblems/Virtual Console twice, so extra conditional statements had to be added for that special case. All of the code related to GlobalProblems/Virtual Console can be seen here.
