It still have some concurrency must be fixed. But I realized the mechanism of multi level have so many adding/removing object in a simulation step (migrate, capture statement of macro micro agents). So most of these errors come from the fact that opengl (or display) cannot draw or access the geometry of a dead agent (which is capture in macro agent or migrated, released macro agent). I ve try with the synchronize button in display , which mean no gap of "living agents" and "drawing agents", it would eliminate some execption.
