I have found this has happened on other web sites in the past.
Always on the third page.
Update: Changing any page name causes Muse to crash.
Any solutions to this?
Many apologies to find you in this trouble.
However, would you mind sharing your .muse file with us so that we can investigate and try fixing it?
For sharing the file you can follow the steps explained here - https://forums.adobe.com/docs/DOC-8652 and send the link to me in a private message.

Link sent, thank you.
H I had a look at your file and found that the was an issue was because of some corruption in horizontal menu placed on Master page.
Try deleting it and create a new menu and should work fine.
Let me know how it goes.
Will do, thank you.
