UE4.11 "it is Pending kill" Cannot create subcomponent in Constructor any more

I’ve tested my blueprint in UE4.11 and now objects cannot be created any more from the Constructor script, but everything works fine, when I move the creation code to the EventGraph - Event BeginPlay. Has something changed in UE4.11. Can someone please explain?

The objects I am trying to create are just NULL-pointers and when I am trying to use them I get errors like:

PIE:Error: Error Cannot access ‘DESTROYED_B_MyObject_CHILDACTOR_358’. It is pending kill. Property: ‘CallFunc_Array_Get_Item’ from node Strike in graph ‘EventGraph’ in blueprint B_PlasmaSphere

This is an example of the constructor, where I store the object in LightningRef for later use. But the LightningRef is NULL.

This is an example of anothet constructor, where I store the objects in an array called PlasmaRefs for later use. But the PlasmaRefs[x] are all NULL.

The message log when running and trying to access the objects is:
