The Issue that I'm having see screenshots happens randomly in adobe applications like Illustrator.

I followed the instruction the adobe support gave me with the link, but there where no issue so I send you the last step, more details. Re-install fonts or Creative Cloud etc. don't solve the problem. I have this problems here and there since more than a year now.

macOS Mojave Version 10.14.02 (Issue appears also in older versions)

The latest Issue I have sometimes is, If I save the Illustrator file and saving is done, Illustrator jumps back 3-4 steps (undo). So after I save I will see a older version of my design in illustrator, which makes working on the artwork confusing, did it save, delete, what happend. After I re-open the file everything is back where I saved it.

Another issue that I run into is that If I select a object a bigger bounding box appears, containing other elements somewhere on the artboard. In relation to that I'm also sometimes unable to select objects and move them, the bounding box moves or the object jumps back to its position.

I can't explain the issues more, I just share my experience and these issues happen randomly so capturing those is like catching air. I taked already with the adobe support and followed all instruction but the team still don't know what it is and how to fix it.

I wish that in 2019 the overall performance of illustrator gets better.

Happy new creative year 2019
