If I recall correctly it means that you have a object defined in itemdesc.cfg as armour for an item that does not have a layer/facing value set.
For example, say it was this item causing the error:
Code:
Armor 0x13C7
{
Name LeatherGorget
AR 12
Coverage Neck
VendorSellsFor 36
VendorBuysFor 10
MaxHP 104
script :combat:equipitem
equipscript :combat:item_equip
unequipscript :combat:item_unequip
}
You would locate item 0x13C7 with InsideUO and verify that it has a facing/layer value set, and of course is flagged at least wearable and as armour.
As to locating which item causes the error, thats the hard and tedious part. Would be nice if the core said which item it was trying to load when it failed. However seeing as the last package loaded was "pkg/world/weather/" I would guess the itemdesc.cfg would be in that package, not sure though.
