Like you Carolina Panther is Platinum and most likely has automatic vacation days. He last played on Nov 14th. For whatever reason, he's been off site for most of a week.

To the best of my knowledge, the automatic day off just kicks in on a day by day basis.

Way back when, when I was very ill, I only had friendly games going and I had it engaged so the games wouldn't disappear, but I don't recall any visibility of that engagement.
