Mobs Indifferent and Drop No Loot

[Nightspire]

Hi all, I'm sure theres something somewhere related to this deep within the boards but I have not been able to find anything specifically on this so I'm posting here.

My server is up and running well, but one of the main problems right now (among many) is that mobs in most all zones (including Korafax, Field of Scale, Valdeholm, Kaesora Library, Korascian Warrens, Buried Sea... and many others) are indifferent, seem to die easier than they should, and when they die, they drop no items at all. No items, tradeskill stuff, no plat - nothing. And since they drop nothing, the corpses poof within about 5 seconds of dying.

Not sure what the problem is, there is only one zone that I've noticed was okay and that was Kael. The giants were kos and dropped regular gear. Any ideas what may cause this?

Thanks!
