The bot limits you based upon skill level, but the game allows you to harvest any node at any skill level now, since the 4.1 patch.
As soon as your character hits the previously required skill level the bot begins harvesting again. The limitation should be removed.
Should be fixed. See this thread: https://github.com/BosslandGmbH/BuddyWing/issues/18Whatever happened with this? We really need the limitation removed now that you are able to harvest anything at lvl1. It's 1000x more efficient to level up your gathering at max level in a meshed max level area than fucking around in lowbie areas, many of which aren't even meshed.
