Direct import of Illustrator files has issues
I'm using the latest of all CC tools on the latest Mac OS.
When importing .ai files directly into the project, I found an issue: when I edit the Illustrator file and save it, it typically updates properly in the Premiere sequence where it is embedded. Sometimes however, especially if I change the Artboard size in illustrator, after save, Premiere updates but shows the graphics in incorrect aspect ratio. If this happens, the only way I found to solve is to quit Premiere and start again. Then it will be displayed correctly once again.
