So when killing the King Wild Dragon located in ~35 Wilderness (fort or whatever it's called), nothing drops. No Dragon Bones, nothing.

My character is a PK'ing account, if that makes any difference. Possibly a bug having to do with not getting drops outside of wildy?

Drops are showing, so it's not that. I thought maybe somebody had killed most of it, so I tried 3 more kills all by myself, to no avail.
