Howdy,
I came across this plugin very recently (just got to 90, hehe) and I have to say that the idea behind it is amazing. Of course I got it and tested it extensively, but I found too many issues to simply ignore, so I decided to tweak/clean a bit the code to make this work without hichups (which now does, or at least for me).
Mainly I addressed the navigational problems, but I also included some druid love (no dismount if you're using Flight Form or Swift Flight Form, afterall, there is no need to waste time, am I right?).
Another thing I addressed was the fact that the Netherwing Egg part was a bit off (for the plugin, Onyx and Netherwing Eggs were the same).
My changes can be seen

P.S.: Hazard, I hope you don't mind me messing with your code mate, if you do just PM me and I will remove the link.
