achievement.cpp has this near the top:

namespace
{

generic_factory<achievement> achievement_factory( "achievement" );

} // namespace

I honestly couldn’t tell you why though.

The problem is I don't handle unnamed/anonymous namespaces yet, this will be fixed soon.

No worries. For the moment I just did this to let it run for longer to see what it generates:

Yes, this makes sense. I'm not sure how to handle anonymous namespaces yet, it should probably be done on a per-file basis.
