Grouped Items Switch Layers

Windows 7, FireFox 12, Flash 11.2.202 I've been losing my mind over this one >.< I'm building a platform out of different sized square images of hexes, and want them to overlap in a very specific way. After I manage to get them overlapping (which is quite hard without a layer viewer!) and set them all as a Group, I can move the platform as one piece, but all the hexes change their layer positions! When I say layer positions, I don't mean the Map, GM, and Token layers, but rather the front/back positioning within each of these. I am building the platform and moving it on the Map layer level, and can consistently reproduce these results. What's more, last night I had them rearranged perfectly and in place. This morning I came back and still had all of the pieces in the right places, but the layers within the Map layer were a complete mess! It took me an age to sort it out, and I never got a red "lost connection to server" banner error (which I also assume is server side as my connection is fine).

I have concluded the issue of not saving was caused by the lost connection to server error that others are experiencing. Thank you for making an amazing online rpg client. EDIT: I am still experiencing the issues with items moved as a group switching layers, which is slightly maddening if you're building complex objects on the map. For now I am getting around it by removing the grid, taking a screenshot, and creating a png with transparent background to be imported.
