When I'm in the midlle of saving a file, (so while I get the progress percents next to the name of the file) if I press CTRL + SHIFT + S, it DISCARDS the saving of the .ai, no warning message as it previously did (something along the lines "The document "***" is currently getting saved. Try again after the process is complete") and proceeds with exporting the PDF, leaving me with an old version of the .ai file, and with a PDF that it's up to date.
