GUID comes from an Xml data file. Are we 100% certain that UIDs will always exactly match on multiplayer games? My assumption is no, so I went with the GUIDs that I am 100% sure will match.
I did use the Mouse overlapping initially, switched to this to see if it would fix. No change.
Frame = 0 is the card back, 1 - X are the card faces. Not sure how else to toggle the visible frame? How else?
