May be annoyed with the cyno a bit, but check parameters. These guys are good indicators. Also, they do close up when shedding and just because it is Tuesday, or April, or 2016, or any reason really. Keep an eye on it and if not open in a week or shows any black (dead tissue), then start to show some worry.
I am not trying to be mean in any way. Leathers are hardy, but can be funny about coming out for long periods of time.
