@TobiHartmann Thanks for your help. I've just updated a new patch. I've just added more code from the original patch to this. Could you test this second patch as you did previously, please? We are completing this a chunk by a chunk so that we can spot which part causes the failure. I think we merely need a couple of patches to do so (this one inclusive).
