Mouse UI: Left-clicking on a position should move the PC by at least one space
Internally walk mode is used to handle the mouse clicks (walk to position). Walking but one space works but if you click at a more remote space you do not walk at all. This is plain wrong and totally not understandable in mouse based play.
This walk mode should always walk one step and it even should post a message somewhere if walk mode is interrupted so that you understand the reason for interruption.
