Hey MezioPleo,

Does this crash only happen when you load a streaming level? What method are you using to load level (streaming volume, or load level node in a blueprint)? Does this happen with any streamed level, or only one? Does it happen in a new project, or only your existing project? Any other details might that might be helpful?

Please and attach project logs after this crash, as well. Thanks!

Hey , I figure out cause of crash, I brainstormed a little bit and this line made me check one of my characters who’s loop was launched at even begin play. I stopped his loop from triggering at start and it seemed to have fixed issue.

UE4Editor!FEngineLoop::…

Ah, an infinite loop crash? Was character in streaming level?

Yes, he had randomized attacks and one of them had a loop that ran 6 times. I think its that loop that got actived upon level stream + character’s event begin play.
