Board Game Arena

I just won my first game of 7 wonders dice, and got the achievement for back to back wins, which actually didn't happen.

You "won" a game where another player quit or was expelled.

That links to 7 wonders, not 7 wonders dice. But I see what you mean. That’s so strange that I’d still say there’s an issue.

That game never even started, a single move was never completed, looks like a lobby was created and then magically disappeared and finally timed out.

Ah, my bad, sorry for not double-checking the forum's name, this is the right page:

It's the same: a game won by another player's expulsion. The only difference now is this was the second game, and the one that triggered the "Bang Bang" achievement. Interestingly, you don't have the achievement for 7 Wonders. I wonder (pun unintended) how the BGA code actually looks like. In my experience, all stats and achievements in BGA are quite unreliable.
