Scumbag solo win

[Hampety]

Not sure where I'm supposed to post this, but I just won a solo game as a Scumbag and gained nothing which felt really sad and got the Witch win even though I never were a Witch :(

So my question is, is there actually any achievement for a solo scumbag win? I got some pics from one of my replays. I just thought it was hilarious how I won and wanted to get rewarded hehe
