I've been playing this game consistently for a long time, and as someone who cares about 100% completion of Steam titles, I'd like to know if this achievement is still obtainable. If so, how?

I upgraded a Dunkel Falchion I bought from Dunkel (Klaipeda equipment merchant NPC) to +15 and successfully managed to fail the upgrade with a regular anvil to +16 and break the weapon, but the achievement didn't pop for me (It already had zero potential when it failed, however, not sure if it makes a difference).

One thing I did notice was that despite using a regular anvil, when my character uses it, the sprite is named my character's name's "Goddess Anvil", which I found weird, because I remember it used to be just a regular anvil sprite before.

I tried to reach support via forums but even the login attempts failed. I'd greatly appreciate if someone could help me out with this, it's been quite the frustrating experience
