Building Error with Paper2D (filename not found ntdll.dll)

Hey,

whenever I cook something with Paper2D enabled I encounter an error about filenames missing.
It only happens when Paper2D is enabled. I tried it with other projects not containing any 2D elements at all which cook just fine without it enabled and exactly the same error occurs.

Address = 0xe82bfde5 (filename not found) [in E:\UnrealEngine4\Unreal Engine\4.3\Engine\Binaries\Win64\UE4Editor-Core.dll]
Address = 0xdd58c4c1 (filename not found) [in E:\UnrealEngine4\Unreal Engine\4.3\Engine\Plugins\Experimental\Paper2D\Binaries\Win64\UE4Editor-Paper2D.dll]

Is it a bug? And more importantly is there some kind of fix?

Thanks
