About 5 accounts have been banned for exploiting this bug, that is fixed now.
These accounts were doing it at an "industrial level" (gathering these same nodes way more than 500 times a week !) and thus gathering a lot of gold/items in a very little period of time.
In such a situation, where you find a trick to get a *lot* of money (or important advantage) in a very short period of time, you should always ask a GM if it is legit before starting abusing it, since you may get banned for doing it afterwards.
To be clear once again, our Terms of Use defines sanctions for exploiters, that we actually apply. However, players that play the game in the way it is meant to be played don't have to worry. Yes, you can still gather veins / herbs without any problem.
