Run Hexen II dedicated server (h2ded) in one terminal window, run client (glhexen2) in another window and connect to the server. When h2ded moves from demo1 to demo2 level, the swords on the weapon rack may be placed incorrectly with their origin_z values messed up. Also possible with the village1 level. The bug is not easy to reproduce: triggers best with first run of h2ded; rebooting usually necessary to trigger again.
See the attached edict dumps from the server and the map's reference ent file to see the broken origin_z values.
