Confirmed, this seems to be serious problem due to double-links into the Octree. The order in which of Undoable objects are restoring their state is important, which should not be the case. This needs some serious thought, maybe a redesign. |

After looking at this, I think introducing handles when linking/unlinking nodes to the scenegraph should prevent double-additions or disallowed removals. Storing the handles in an efficient way to minimize the performance impact is a goal. |
