Not actually sure if this is a file save issue or a UI issue. I've been working on a drawing for a few days (24.0 on Windows 10) when at some point, after a save, the location of a lot of the text objects is corrupted. Open the same file in Acrobat DC (for PDF) or browser (for SVG), and it looks fine. In Illustrator, not so much. Have replicated it a number of times, working in .pdf, .svg, and .ai formats. It's a show stopper, not sure how to proceed.
