I am halfway through an animation in After Effects CS6 using Illustrator asset files (all layer size). Some of the assets suddenly appear to have gone missing, so I replace the file and on the import box, the default is now set to document size. I click layer size and click replace and it sorts the problem. Has anyone else had this problem and is there a quicker way to replace all the missing files or change them back to layer size? As i have quite a large list of assets that have done this.
