I'm having the same probs here. and the file fails to import ti IC8
Seeing the same thing in this scenario: With a ccProject file open in CC4, after exporting the character to an iAvatar file, the title bar shows the current file to be the .iAvatar file that was exported (instead of the ccProject file) Also, while you can still edit the character, you can no longer save the ccProject using File->Project Save. CC4 version 4.22.1612.1
