other bugs I know of:
1) "twitching" when moving. the bot seems to twitch when running. an experienced player can notice this very easily and report it, which will lead to a ban.
can't be fixed. about 15 years ago I played on official servers, and I remember this oddity in some players, even then I knew it was a bot. i.e. this bug is decades old and no one is fixing it.
2) regular crashes. about once every hour or two it will definitely crash. it may be random like every 10 minutes or 30 mins etc. the wow client crashes, but only when the bot is running. without an error, the wow client seems to close alt f4.
3) not a bug, but it is very annoying that I cannot draw an area in the black list editor. this would be MUCH more convenient than selecting a radius.
4) does not apply to the bot itself, but still: the move during combat plugin stucking. the stuck usually occurs after ~ an hour or earlier. the bot starts jumping non-stop in combat, jumping over the monster over and over until it kills it.
if you haven't removed the jumps from it, it's a 100% report and ban. with the jumps removed, it starts spamming one move every ~second. it still looks weird, but not as dangerous.
5) no option to stop the bot when it's teleported. but for some reason there is an option to close the wow client. i.e. when the bot is teleported, the wow client closes and you get a ban.
this is just what came to mind, but because of these bugs, you can't leave the bot longer than 15 minutes. I can't imagine people leaving it unattended for longer.
it needs to be constantly monitored, otherwise you'll get a report and/or a ban.
