I am getting multiple errors.

The biggest issue, is the section book is completely broken. I can't choose what page to go to, the hidden areas are all gone. Every time you interact with it, you get this error code "Error in Script (Section Book - 68f04a)function <onLoad>:chunk_4:(222,2-46): attempt to index a nil value"

I am also getting other scripting errors in other places, such as trying to bundle the campaign for export (and nothing happens). Any ideas how I can fix this?
