Event flow is faulty at the cave where you meet Rags for the first time. You softlock the event when you talk to him and picking the exit dialogue option without asking to see his products.

Event flow is faulty at the party when you choose to bribe the bard for a poem.
In the same quest that involves the guy, you are required to give him an apple tart the recipe you receive doesn't enable you to craft it.

Missing file.

The collective after convincing the magus a battle tries to start with the collective but "Unable to find file: Audio/BGM/Battle_-_Angry_Avenger_LOOP"

After naming an audio file after the missing file's name the event continued but after defeating the collective the magus is uninteractable.
And I have a feeling the event got simply cutoff after defeating the collective.
