Did a fresh install of WordPress 4.5.2 on my server using the exact same setup as a 4.6.1 install to verify it was/n’t an issue with my server configuration. It appears to be an issue with 4.6.1.

Created 9 pages without issue on 4.5.2 and as soon as I upgraded and started 2nd new page it used the permalink from the previous page.

This post goes one step further and shows there an issue with the get_permalink() function.
