What does After Effects: CT bad param: invalid glyphID ( 83::2) mean? I'm working in After Effects Version 15.1.2 (build 69), as I was typing the application froze and this dialog box appears, "After Effects: CT bad param: invalid glyphID ( 83::2)". Why? What does that mean? I've researched online; in mean-time, I improvised by grabbing outlined type from an Adobe Illustrator. How do I fix this problem? I would much have rathered to type the text then copy & place in the position of the original layout.
