how did you even got 20 liebeth affinity i can only get 18 from 1 node and i can’t find another one.
Look nearby, to the upper left of the one you found.
And for some reason, in one of the games I played in the new version, the Demo Lord showed up after boss X, rather than IX, which is why I didn’t get the mysterious invite in that game. Worked fine in a subsequent game.
