Enormous issues with Illustrator 2019, OS High Sierra
Illustrator 2019 is acting very strangely. If I undo once, it goes back several steps and I cannot bring back those steps. It removes layers and artwork without any actions. When I save, it removes several actions every time.
If I quit the program completely and restart, it acts normally for a few steps and then starts the whole disappearing act again. I have re-installed the program a few times recently but the same thing keeps happening. It's extremely time-consuming and frustrating!
