Board Game Arena

I played this game https://boardgamearena.com/table?table=486954494 and bought the hammer on one of the first rounds. I had auto hammer for my gold coins set up and the hammer appeared to fill over and over.

Yet at the end, I got zero point for my hammer!

What is up?

Hammer points are scored during the game, not at the end. It can also only fill up twice, not over and over. I see your opponent Little-Dinkey completing a hammer twice and scoring points for it. The moves list doesn't seem to show when coins get moved onto the hammer, so I can't say much else about what happened, as it won't show the live replay any longer, just the text list.
