Saving it with a different name does not fix the problem, still persists.

Ctrl-clicking in the TOC works fine, and takes me to the page as expected. Double-Clicking does nothing, but that's expected as well. In order to "jump" to a page from the TOC, it needs to be a Ctrl-click, not a double-click. But again, this is fine as expected.

What is broken is the Ctrl+G > Page functionality.
