i used an anvil with full inventory and lost my heavenly sword.

the title sais it all, i was just done with filling up my inventory with enchanted books from the enchanting table upstairs, and i thought... hey might aswell repair my sword whilest im here. so i used the anvil with my sword and at the sametime i accidently picked something up, so when i was done repairing it just vanished from existance.

SS of my sword from inventory but you cant see my enchants will be attached.
