Bump, c’mon guys. :I
Hi ThatQneNoob,
Packaging fail can really be a pain in the aXX for me sometimes, because most of the time it’s hard to pin down the real problem just by looking at the output log.
I’ve downloaded your log file, by using search error function, I’ve noticed some fishy log output, maybe these logs can give you a clue:
Line 178: [2017.07.13-22.58.30:770] 0]LogOutputDevice:Error: Ensure condition failed: ParentNode [File:D:\Build++UE4+Release-4.16+Compile\Sync\Engine\Source\Runtime\Engine\Private\SimpleConstructionScript.cpp] [Line: 872]
Line 230: [2017.07.13-22.58.31:334] 0]LogBlueprint:Error: RemoveNodeAndPromoteChildren(SCS_Node_32) failed to find a parent node in Blueprint /Game/House.House, attaching children to the root
Line 281: [2017.07.13-22.58.35:513] 0]LoadErrors:Warning: Warning CreateExport: Failed to load Outer for resource ‘Arrow’: ThirdPersonCharacter_C /Game/AI.Default__ThirdPersonCharacter_C
If you still have trouble finding the cause of the problem, I will suggest try packaging an older version of your project or try packaging a clean project to better identify the problem.
From my personal experience, I usually backup my project every 2~3 days, and packaging and testing a cooked build before backing it up. This habit will ensure you have the latest
bug free, distribute-ready version of your project.
Hope this helps.

This is the error I was referencing in the title. What does it mean? How can I fix it?
Sorry, I don’t know what that really means. 
However, by looking at the log error stack, I’m guessing it’s caused by the second error I mentioned earlier:
Line 230: [2017.07.13-22.58.31:334] 0]LogBlueprint:Error: RemoveNodeAndPromoteChildren(SCS_Node_32) failed to find a parent node in Blueprint /Game/House.House, attaching children to the root
hence, “Ensure condition failed: ParentNode”
Could you perhaps fix the House.House missing parent issue, then try packaging again?
I may have fixed it. All I did was make a new project and move over the Content folder, and now it is packaging flawlessly (So far, I’m writing this as it packages.) It’s gotten a lot farther than it did last time, so I think there was some sort of source file missing in the first one.
