No access to page 60 of a thread

Hi.
I hope you're fine
 
Currently we have an issue at our most active thread:
http://colombianosalcanada.lefora.com/2009/04/03/llegada-de-visas-abril-junio-2009/13563094/
(you can't see the message located at page 60, and in exchange you are redirected to page 59)

just until today the thread had 59 pages:
http://colombianosalcanada.lefora.com/2009/04/03/llegada-de-visas-abril-junio-2009/page59/
 
Just after two new messages weere written into the page 60, they were "blocked".
 
We can´t access the page 60 and its two messages, so we had to make a new thread for continuing the subject.
The "invisible" posts are visible through RSS but we see the NEW messages indicator and we can´t access them.
(I had to close the thread to stop confusion)
 
Thanks for your help!
