I spotted this behavior working in the transition phase between V5 and V6.
We have to keep our files in one project V5 to stay compatible with our clients.
It might happen that we open files in V6 and “save as” V5.
We created Layer States in the original V5 file. Now here is the rub:
If you open a V5 file with Layer States in V6 and “save as” V5, Layer states are all gone.
Data loss so to speak. Especially annoying when you find out days later when there is no easy way to recover.
This behavior is reproduceable.
Try opening the attached file with V6 and “save as” V5 and then check in V5.
