I don't remember what chapter it's on, but Sofia takes you to the forest to fight some beasts who were in reality cows, only for one of them to turn into Myrr. After killing him, I was teleported back to the base with nothing else to do, as talking to Sofia again restarts the sequence of fighting Myrr. Sorry to say this, but I felt compelled enough to go into the game's code to edit it, so that finishing the quest worked properly. Afterwards during the horse race, you have to interact with the floor to leave the cave after fighting the cave beast. The floor not teleporting you as soon as you touch it was very confusing!

Sorry, I think I've been confusing the character's names. I'm talking about the girl who calls the player stinky, and I couldn't speak to the leader after finishing the quest with her to progress the story because no dialogue changed. She wouldn't say the line "now go talk to Kosaka" no matter what, if I spoke to her again it always sent me back to the forest to kill Myrr. If I spoke to the leader, he would only prompt me to start chapter 3 (which is the chapter this bug appears on).
