Yeah just certain shops aren't working.
Could it be a matter of permissions to access that shop?
I mean, it does mention 'Cysero' in it.
I'm pretty sure it would be the shop locationlayer location prevention if anything.
About the pet thing, I highly doubt you have managed to find something, it was probably just a coincidence that a test of yours worked. Elaborate and I might change my mind.
You mentioned that you want to hack AQWorlds "server sided" but if you really mean that, I would be extremely careful. Remember that sniffing + editing packets doesn't mean you're server sided.
I don't mean to be critical, but all this seems a little rash, and having seen you post multiple help threads in the main section rather than the help section, kind of makes me doubt...
