I’m having problems cooking content for packaging. This is the error that stands out to me

MainFrameActions: Cooking (Windows): UE4Editor-Cmd: Assertion failed: NumRemoved == 1 [File:D:\UnrealSource4_10\UnrealEngine\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectHash.cpp] [Line: 569]

Or maybe it’s something else, Can anyone help to explain why?

Thanks!

Currently using 2013. I’ve been building the engine from source though and this compiles fine.

3

Visual studio is updated right? (2015)

4

me too, and suddently I couldn´t cook or package anymore, so I downloaded the Visual Studio comunity 2015 and updated, installing everything (common tools too), now it is working.

Sooo, you should do the same my friend! Good luck!
