[PCG] Undo a pcg actor delete remove graph

Hi UDN !

It seems that there is an issue when we undo with Ctrl+Z after a PCG actor delete.

The actor is back, but the PCG graph seems corrupted as the PCG graph parameter is not visible at all, so the PCG graph can’t be generated again, we can’t assign a new graph either as the entier PCG graph parameters section seems gone.

In the repro I sent, the graph can be set back if we desactivate the component and re-activate it. BUT, in our production tools, even doing this can’t make the PCG graph bake again. ( Tools I wasn’t able to isolate easily in a repro project sorry … ).

So in our case, it means that the actor is gone for good, I could’nt find a workaround to make it pop in again (well, other that re-loading the map of course).

Thanks,

Guillaume

Steps to Reproduce

  • Drop in a world the actor: TestActor (found in \Content\UndoIssue)
  • Undo with Ctrl+Z
  • The PCG component seems “corrupted”, no graph parameter or graph instance parameters can be seen
  • The PCG graph can’t be generated again nor the graph re-assigned.
