@Kapow I'm assuming that she slipped between some trees that they couldn't get past due to the denseness of the forest and thus couldn't catch up. That, or God pulled some strings to ensure she met with the goblins on her own and thus allow her to mediate the situation since her power makes her loved by all nonhumans, which as mentioned by some others in the comments includes goblins, kobolds, etc. Of course, this is just a guess(since I don't remember if her power indeed included absolutely all nonhumans, including demons, goblins, and whatnot) and as such it's possible they may not love her and might try to hurt her, but we won't know for certain till next chapter and the goblins loving her sounds better anyway.
