So, we have a DNN site that is still in 3.x.  It was upgraded there and left for me when I started working here, by someone who picked the only 3x version that doesn't upgrade worth anything.  Anyway, it's been here for well over a year, but all of a sudden, last week, it started having layout issues when new pages are added.

The new pages don't have different skins and every page in the project uses the same layout from the main of the site.  Their weird part is that the layout is pretty simple.  The site only has a title section, links, 3 columns (left, right, center) and a bottom section of by lines.  For whatever reason, these new pages mess up the sizing for the 3 body columns.  For instance, the left column will grow and squish the center and right as if there were too long of a string entered into the field... except the left column is the same for all pages.

This is all really weird and I don't know that I can explain it exactly, but if you have any ideas, please let me know.
