the file I saved shows an old version of the art when I opened the computer today. yesterday I clearly saved the newer version and checked. i literally did nothing in that time period
I'm sorry, but this is not a user support place. Your report provides nothing to help figuring out what is going on. Please see https://docs.krita.org/en/untranslatable_pages/reporting_bugs.html on how to report actual bugs. For support, ask fellow artists on krita-artists.org -- but unless you provide way more information than you did here, they won't be able to help out and figure out what's up.
