We are running stock Chernarus, running DayZ 1.7.4.4 on the latest official Hive version. Mind you, this is a public OFFICIAL Hive server, so Bliss,etc,etc has nothing to do with it.
I'm a co-Administrator on Shadowwolf's server, we are running a Public Hive server so DayZ Tools doesn't apply in this situation. Far as I can tell it is a bug with InstanceID's above 8000 or so. If anyone has any other answers, we'd love to hear them (or from someone in Support).
