You need to go to Settings & Tools and disable Attack Between Hotspots. The only catch is that this -may- cause you to not attack the special mobs that spawn from some flowers, such as the withered from roses.
I'll give you guys a hint. Check your settings
Thanks a lot nemisawesome! Some of us are beginners on HB stuff lol, never used gatherer before.
And the thing is, I couldn't find this information anywhere, and there's like 5 or 6 different places with ppl asking.
and well, I unchecked but it still dismounts =/
edit: if I have aggro on me it won't try to gather, it'll get to the node than run back to fight. I wanted it to gather and run away. And if could detect and fight an spawned mob from the node it would be ideal.
