    yields:

    Code (CSharp):

    This error happens in like 1/20 or so scene changes and might possibly be related to me destroying the entire default world and recreating it? So maybe an ECB is running on a disposed world.
    This is the code I'm using:

    Code (CSharp):
    1. public static IEnumerator DestroyAndCreateDefaultWorld() {
    2.             /* Destroy the default world: */
    3.             var defaultWorld = World.DefaultGameObjectInjectionWorld;
    4.             var entityManager = defaultWorld.EntityManager;
    5.  
    6.             entityManager.CompleteAllJobs();
    7.  
    8.             /* Destroy */
    9.             entityManager.DestroyEntity(entityManager.UniversalQuery);
    10.  
    11.             yield return new WaitForEndOfFrame();
    12.  
    13.             /* Disable all systems: */
    14.             foreach (var system in defaultWorld.Systems) {
    15.                 system.Enabled = false;
    16.             }
    17.  
    18.             yield return new WaitForEndOfFrame();
    19.  
    20.             /* Actually dispose of the world: */
    21.             defaultWorld.Dispose();
    22.  
    23.             /* Take it out of the player loop: */
    24.             ScriptBehaviourUpdateOrder.RemoveWorldFromCurrentPlayerLoop(defaultWorld);
    25.  
    26.             /* Reinitialize the default world: */
    27.             DefaultWorldInitialization.Initialize("Default World");
    28.         }
    Again, not sure if it's related to the crash even, but I figured I'd add the snippet.

    This has worked without a hitch during many many hours of debugging and testing in the editor, but in the Android player it will crash about 5% of the time.

    Anyone has a clue on how to approach this?

    Thanks,
    Nico
