For my part I got this crash code when rendering out with MRQ - it was that some Blueprint Actors that were referencing something that would spawn during regular gameplay, but not when render out an animation. Regular sequence renderer seems to just accept the null value that this generated, but MRQ crashes the entire engine :frowning:
