FSM diagram bug

When I create some complicated FSM diagram with a lot of states, substates, and regions, the diagrams start to behave very weird. Resizing one region, causes unrelated components from another region to move/resize in totally weird manner, reloading saved diagrams places elements in wrong places (each time I open diagram it loads differently!).
This is quite annoying for serious application such as this to have this kind of bug.
