Freeform gradients color stops were altered after crash
Running Mac OS High Sierra and Illustrator CC2019.
While editing one shape with a freeform gradient, Illustrator crashed. Document had been saved prior to the edits. When opening the recovered file, all objects using that freeform gradient had all their color stops altered. Instead of dark brown, med brown and yellow, color stops were changed to use Registration, an unnamed brown and an unnamed pale color. None of those colors matched what had been used prior to the crash. Had to manually go back and redo the freeform gradient.
This feature is going to be really useful but you have to make it work better. Not being able to create a swatch for it, not being able to use Recolor Art and now possible recoloring of itself due to a crash makes me cautious to use it right now.
