I just opened up a Photoshop file that heavily uses these artboards in photoshop and I'm having the same problem. I worked on this project 5 months ago and was able to adjust the X position value to move the board exactly where I want it. Now I can't do that since it'll only move the artboard and not bring the contents with it. Sure I can move the artboards with the move tool but it won't have the accuracy I loved with the X position value. It's extremely frustrating! Photoshop fix this please or give us a work around!
