Did you replace items.otb?
Sorry, but I'm unable to guess what kind of clusterfuck version combination you got there.
You have to change items.otb
Hi, do you have Zao on your map? If so, does it look weird or okay?
About the helmet/flag, nothing important. It bugged because you changed ID's, you can still execute a few queries if you want to update the ID's in player inventory/houses/depots.
