It's not your fault, it's ours. Well, not so much ours, as Gnat's. At least, I'll assume it's Gnat's. This seems like the kind of thing that would be Gnat's fault.
Unless there's gremlins. They can be a real pain. They get into everything. Seriously. There was one going through my garbage the other day. I had everything stacked nice and neatly for the garbage truck, and it came through and just shredded everything. Like a green, fuzzy tornado.
Yeah, that sounds better. Let's blame this on gremlins.
If you don't believe the gremlin story for some reason, I suppose you could send an email to the administrator at firstname.lastname@example.org, and let us know where the problem is.
But seriously - gremlins.
