[Scribus] Page numbers disappear

[Femke Snelting]

Hello!

I am currently working on a 70+ page document and halfway (after page 
47), the page numbers have suddenly stopped appearing. I hope anyone 
here knows where to look or how to solve the mystery.

I'm using 1.3.3.4; pagenumbers (##) are placed in a textbox on a 
right-hand masterpage; the document has facing pages; page numbering is 
placed on the right side only.
I'm probably overlooking something silly; this is what I've tried up 
until now:
- delete the pages with problems, re-insert them
- re-applied the masterpage
- deleted the page numbering from the masterpage and re-applied
- deleted the left-hand masterpage, re-made it and re-applied it

The current version of the .sla document is here:

best,
