As far as I know a cursed player will only give birth to another cursed player. The only people with black speech bubbles are cursed players. How did a cursed player wind up in your town for you to see this?
Wow! Maybe it’s a glitch? I’d hate to be born to a griefer right after they’ve accumulated enough points to earn Donkey Town status if it marked me! No wonder she wanted to die!
It might well be a bug and @Christoffer may want to see a link to the family line to investigate.
You are actually very good at English! It may not be a case of trolls escaping as much as it is there are a LOT of trolls! I’m just surprised a marked person was in your village to begin with.
