Welcome!

If I ran the bot for 12 hours (according to the payments made) and when I check my account xp, I gained only about 500-600k, is bot defection a reason for the time wasted to be refunded, or is this something that's just part of using premium bots and there's no compensation for defective bots...

I don't really plan on doing any other botting other than for maxing melee/range. I did a search for NMZ/instances in the search function, but nothing came up, so my apologies if this has already been discussed. What's the likelihood of being caught in an instance? I would assume people...
