Let me poke some more people to see if they can help here with some other points of view (although I don't know when/if they will respond)
@Plailect ; @Quantumcat ; @KunoichiZ ; @gnmmarechal ; @gamesquest1 ; @astronautlevel and other's who may see this, can you help to solve this?
There's no hurry, it's just that I've spent hours trying to get this exploit to run and it's beginning to frustrate me a little. I'm still clueless as to what the route of the problem is!
