Save down to CS5 from CC 2017 loses layers
I have the latest version of Illustrator, CC 2017, but not everyone at my job does, so it is necessary to save down to the lowest version in use so everyone can access it. In our case, it's version CS5. When these users open the files, all the layers are compressed and any graphic styles applied are expanded. Curiously, this only happens if the files are saved in the native AI format. I can save them in EPS without seeing these issues, but the EPS is nearly twice as large and we already have issues with drive space. Please patch this soon! Examples of layers before and after are below: CC 2017 on the left; file opened in CS5 on the right.
