I just want to say that after reviewing some of the demos, the exploit is not appearing on the demos. This is most likely due to that I starting recording after the they did the exploit and the demos didn't pick it up. So the RDA demo is useless.
But also shown in the end of the 'promotingexploitsUncle' (around 9:00) that Uncle does know the exploit and RDA used it, I just wasn't spectating him.
Now 'uncle' is extremely laggy and suffers from the same problem as mentioned, and I couldn't load up 'uncle2' for some odd reason. So it might be the same things.
Sorry in advance for anyone coming to this report, I need to review my demos more as I've been slacking on that.
