Some items are currently bugged and don't display in game or on webpage. They are saved in the db just fine so nothing is lost, it's just the issue of displaying them correctly. We are working on fixing the issue.
Possibly affected items (there could be more):
Bardiche
Long Espada Eslavona
Langes Messer
Goedendag
Dadao
Great Axe
Great Sword
War Cleaver
Shortened Military Scythe
Italian Falchion
Torch
Light Strange War Mask
Heavy Strange Helmet
No refunds are possible. You will get the item once the bug is fixed so nothing is permanently lost.
