HAVING THE SAME PROBLEM. I have a master Ai file saved on my HD. I made a new one in Illustrator 2018.
Copied my art from the old file to the new file. So far it seems to be working. Haven't seen that pop-up saying file was modified outside illustrator. Whenever I start a new job I always go to that master file. I have the palettes for of all the symbol, brushes colors etc., cleared. Hope this helps.
