i notice two points that can be improved:

1: If you use the NavMesh Tool in WorldEditor, to rebuild tiles, the workflow will be much easier if the NavMesh-Map in the Window will be automaticle centered to the current Camera. So, you do not need to search the whole Map for the current Position.

2: Since i added the Updated tiles NavMesh to "NavmeshWorldComponent -> Override" i got and Error while compiling Scripts. "There is more then one "SCR_AIWord" in the world. But, there is only one!
