Easily replicated
Go to a chapter with no prose and populated scene beats
Collapse the scene beats
Add or delete a line between the scene beats, the page jumps to the right.
The carriage return is added to one of the closed scene beats.
Which is where NC thinks the cursor is....only it is not....
Even when cursor in indicated as being between closed scene beats.
The page jumps
Not all the time
Only around 75% of the time.....
Am sure this will occur in many other scenarios'....but, as I am working on scene beats currently, it kind of stands out as I need to keep dragging the page back to the left....
