Hi, first of all, your issues are nowhere related to what we all want to know at the moment. People are complaining about GatherBuddy risk and farming in general. Your issues are leveling related and they can easily be worked around.
Now, DungeonBuddy has a lot of bugs. For some people it works miracles, for others, like me, it never works. I've heard you have to download the HB Beta version for it to work but I haven't really given it a shot since I simply dislike DungeonBuddy. If anything, read the posts on it's thread.
Second, if something doesn't work right for you, use something else. Be pragmatic and efficient. You have a working alternative, questing bot, and when that stops working just grind up a few levels, and if that doesn't work then do BGs which do give a lot of experience.
See, 3 solutions found to one not working.
Cya.
