So, unfortunately while using `\testpage` helped in the version of the resume I was working on at the time, I've encountered the error again now that some different content is making the page break at a different point, and setting `\testpage` as high as 6 is not fixing the problem. Is there something else I can/should try?

For the start you can show us a minimal example with the problem.

When you're still trying to create a paragraph with different text widths there are limitations. TeX always typesets more text than it can fit on the current page and when on the next page the text widths changes this is to late for TeX at this moment because the text has already been set with the width of the previous page.
