No, but it sounds like you're 13. I'd like to think that someone pulling an "inside job" at jagex would do something a bit more spectacular, like if you talk to the mean guy with a coffee and then fly to cinnabar island and surf on the side of the island, a weird missingo would appear and the item in your 6th inventory spot would miraculously have 150 more. ..I.. Uhm. What? You're claiming that the 150 item duplicate was 'miraculous'? Start developing for a limited piece of hardware and you'll understand why these things happen when you have to tweak every piece of data. On the topic of mistakes, I believe it was an honest one. They didn't do any of this on purpose, mistakes are far too easy on such a big project and when faced with a deadline.
