I'm noticing that at some points in Chapter 2, sprites are having errors being loaded. It usually says something like "Image 'neru speaking' not found" or "Image 'neru neutrald -speaking -speaking -speaking' not found". I doubt this is intentional.
This is from some changes I made while adding expressions back to the Prologue. I forgot to account for the effects it'd have on Chapter 2. I'll release a hotfix for it soon.
