TSoftObjectPtr Referencing Placed Actor can't be Resolved
Two things I’ve learnt about using TSoftObjectPtr to reference Actors placed in the world.
- The first thing is if you want to check if it’s set, check its AssetPath and SubPathString from its TPersistentObjectPtr. 
- The pointer may not be able to get resolved even after the placed Actor’s BeginPlay. You can try to set a timer and keep checking after 1 or 2 seconds.
