Thank you for contacting support team.
We do understand your situation. However, we regret to inform you that there is no possible option to retrieve your lost anvil and silver after teleport to other map. We highly advice to please careful next time in enhancing an item to avoid this kind of incidence.

I assumed this would be their response (if they gave a response), but still hoped for more from them. Can we at least fix this bug please then? It is not expected in these types of games that a player will lose any money on a consumable until AFTER that thing is consumed. Let me repeat, I did not use the anvil to either succeed or fail (it’s from +4 to +5 anyway, so that should be 100%), the anvil simply disappeared. How would you ever not account for that in your programming? Did you simply program to see whether the menu closed without the player cancelling? Why would you possibly take silver from a player prior to hitting the anvil? Really disappointed here boys…
