suggestion: entity references / entity containers (specialized NativeHashMap<T,Entity>)

at the core of my design are

Code (CSharp):

1. public NativeHashMap<NodeKey, Entity> Lookup;

and

Code (CSharp):

1.  
2. public struct North : IComponentData { public Entity E;}
3. public struct South : IComponentData { public Entity E;}
4. public struct East : IComponentData { public Entity E; }
5. public struct West : IComponentData { public Entity E;}
6.  

But I'm spending a lot of time ( development time for sure, runtime time probably !) to check if these entities are still valid and to update their values.

I think the concept of "entity references" should be handled by the DOTS framework and not by the game developers.

But if someone wants to share a generic solution for that I'm interested
