I’ve got a blueprint Actor with a PCG Component.
But I’ve found that is spawns a duplicate of the PCG results but in a different location in my world
this only happens with a PCG inside of blueprint.
I think this is a bug, and it’s happening to more people than just you. Typically when you reload the level the other duplicates are gone. Hopefully it’s going to be fixed in 5.4 releasing at the end of this month.
