when sending an image in Photoshop CC from LR 5.3 after cropping by "Modify in", the cropping is lost in Photoshop CC ! And nothing repairs that. After checks, all changes are lost. Same result with "open in smart object".
All softwares are updated (LR, PS and creative cloud app) on Mac OS 10.8.5 and also on Windows 7 64b.
A demo video here
It seems a recent bug.
