1. Assertion failed: [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 2498] UObject() constructor called but it's not the object that's currently being constructed with NewObject. Maybe you are trying to construct it on the stack, which is not supported.
