Freeform Gradient points disappear
I experience a problem with freeform gradient tool after updating to the latest version of Illustrator. The issue is objects with freeform gradient applied become uneditable after saving and reopening the document. This only happens to the freeform gradient tool, other gradient tools work fine.
When reopening the document, the rectangle (number 1) still shows the colours I chose but the freeform gradient points are not there to edit.
The rectangle apparently has been masked and when I release the masking, it becomes rectangle number 2, and still uneditable. It appears like an image.
I've never experienced this before. Can anyone give me solutions and advice? Thank you.
