hi! i was learning some unreal stuff using a book called “Learning C++ by creating games with UE4”
ther is this chapter explaining the creation of an NPC using a Character class,
after creating the new class i need to add 2 properties:
UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category=Collision)
TSubobjectPtr<class USphereComponent> ProxSphere;
and
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=NPCMessage)
FString NpcMessage;
So, if i add only the FString and compile everything goes fine, if i add then the collision component it crashes on compiling and if i reopen the project it does not load at all and as i noticed it crashes al 70% project loading.
Here is the error showing on the crash report

The book uses 4.4.3 i’m using 4.8.3 using Windows and VS Community version, i guess is a compatibility problem but as i’m learning UE4’s api starting from now i actually don’t know how to spot the problem.
Thanks
