you never played wow yourself, huh? ofc I do, not every single day, and not without bio / food breaks, but believe it or not - yes I was farming 10h / day (even more few times).
ah and about you (or some other dev / mod - you're all the same person to me) saying it's caused by the bot passing the same place again - i did some testing, after crash I relaunched wow manually and started to move around for around 20 minutes close to the place where I got black screen, as you can guess - nothing happen. then I moved my char like 100 yards back, and run bot again (do you see where this is going?). cba to continue - It might be WoW issue, I'm not saying it's not but it's caused by HB. I know it, everyone else having this issue know it and you know it. end of story.
I've also tried to edit profile with black spots - not helping.
and about 10h farming - this is happening after 15 minutes of bottling. (if I restart it and run bot right away it happen instantly).
so please, stop saying it's WoW issue, no one would mind bug if devs say smth like "we'll try to fix it" but don;t be surprised with lots of h8 when you're keep saying "it's not our fault, we can't do anything about it" (paraphrase).
Also remember that OC users are not dumb, and sooner or l8er they'll notice you just making fool of everyone (w8 that actually already happen).
