[Minor bug] InvalidOperationException while GameObject with RVOController is selected in Inspector

I was testing local avoidance and ran into an exception as soon as I started adding RVOController to my GameObjects. It took me a bit to figure out that the exception actually only occurs if the GameObject is selected in the Inspector, and I was able to reproduce it on the RTS example scene as well.


  • A* Pathfinding Pro 4.3.94
  • Unity 2023.2.8f1


  • Open the 4.3.94\RTS example scene
  • Enter play mode in the editor
  • In the Hierarchy, expand “Large group of units” and select one of the units
  • You should immediately be spammed with the exception below:

InvalidOperationException: The previously scheduled job JobDestinationReached1 writes to the Unity.Collections.NativeArray1[System.Int32] JobDestinationReached1.output.numNeighbours. You must call JobHandle.Complete() on the job JobDestinationReached1, before you can read from the Unity.Collections.NativeArray`1[System.Int32] safely.

The exception stops if you disable the RVO Controller component.

Thanks! I’ll include a fix in the next update.
