When you use the first time any profile, make sure you babysit on it for at least 15-20 minutes to make sure things like this don't happen. If that herb is bugged, no one can catch it and your bot doing his circuit will pass on it and will try to grab it. Just blacklist!
Another thing, Herbs/Mines disappearing in front of you, it can be another botters using that hack to run really quick and underground, just catching herbs.
Make sure when you see that, to pop your nameplates and you'll see it.
