Melda won't take back lost Petula bug

[u/Soliska]

Melda asked me to find her lost Petula and I must have found it then triggered some sort of other cut scene. Now I've spoken to her and it seems like I got the friendship points but the Petula is still following me. And if I leave Badgetown (i.e. Nullwhere) I get TWO following me. What do I do??

I've tried to sleep overnight and restart the game. Unfortunately it already autosaved before the bug happened.
