Editor Crashes after Project compiles

Development Programming & Scripting
1

Hi there, i got the following Problem: Code Compiles, editor starts, but i get that error and no idea why, it compiled and worked without problems for a while. Then i changed another class and → crash. ( maybe hot reload problem, i added a class, it crashed, but no idea if it is directly connected to that)
Point being: i figured there is a problem within “AItemManager” where i try to spawn all (only 20 or so) items in my game, so i can reference them later on. But: even if i throw that part out, i get this error… and i have no idea why.

Maybe Important: it always crashes at 70% Initializing the Editor

Hi ,

Can you attach / link to the code for this project? I’m mostly interested in the file that contains the ‘SpawnActor’ mentioned in the beginning of the callstack in levelactor.cpp (UE4Editor_Engine!UWorld::SpawnActor() + 433 bytes [d:\buildfarm\buildmachine_++depot+ue4-releases+4.7\engine\source\runtime\engine\private\levelactor.cpp:232])

It could be the location of the function or what is surrounding it but I won’t know until I can take a look at the code.

Hi , thanks for your time!
It’s supposed to initialize the ItemList (TArray ItemList;)

void AItemManager::InitItemList()
{
   	UWorld* const World = GetWorld();
if (World) {
	//First Weapon - Krautbeutel
	ARangedWeapon* Krautbeutel = GetWorld()->SpawnActor<ARangedWeapon>(ARangedWeapon::StaticClass());
	Krautbeutel->ObjInit("StaticMesh'/Game/Objekte/Kräuterbeutel/kraeuterbeutel_006.kraeuterbeutel_006'", "Blueprint'/Game/BluePrints/Krautsack.Krautsack'", 150, "Krautbeutel");
	ItemList.Add(Krautbeutel);
}

}
Maybe it’s worth noting, that it won’t start the editor from visual Studio anymore, it loads, goes to “select level” there i select the level and then it crashes at 70%^^

edit: added some code to check if World exists, doesn’t help… Oo

EDIT: i updated to 4.8.2 and it works ^^ thanks anyways
