I am having difficulties with this as well. Version 8 doesn't connect to the offset server so I am trying to use version 17. This version seems to repeatedly say "we are stuck on ground" even though I am flying and in an open area. It also just flies over herb nodes and seems like it just actually wants to leave the zone.
I'm a bit confused but willing to work with anyone that wants to help.
Thanks.
EDIT- Enabled "Flying Harvesting" and now it is working just fine. (I thought that would be a druid option, oops)
