I've used Gatherbuddy 2 for a while, and I know how great of a bot it usually is... but now it's almost unusable. It'll most of the time just fly around skipping over nodes. Then, when it finally stops and thinks about it for about 15 seconds, it'll go to a node if it's closeby to one. It takes it a great deal of time to finally figure out gathering the node and finally remounting again too. I looked around and haven't come across anything really official regarding these issues.
