Here are some observations I made - hope it helps in some way.
Bug report: The multi doesn't reset with 3 or fewer players. You get full gold and xp even if you're alone on the server. (Tested on battle/EU1)
You can duplicate your first-in-slot item by sheathing it. The duplicate item bug seems to only occur when the server has 3 or more players on it. (Tested on battle/EU1)
Item bugs: "Onion Top Bascinet", "Crusader Face Plate", "Dark Full Face Mail Coif", "Dark Mail Coif" and "Iron Skull Cap" have no model.
"Ornamented Sugarloaf Helmet" is not mapped correctly. (Floating helmet)
