NetherWing Phasing issue

the entire netherwing area in shadow moon valley is a buggy mess. i randomly phase in and out of Netherwing dragon, fall off my mount (still mounted), phase back to my normal dragon riding mount, then back to not mounted (game shows im still mounted) to my death, every few minutes. this area is awful to navigate. sometimes ill be low to the ground, and ill click re re mount ( the button shows im mounted so i need to click to unmount, then click again to remount)

i assume this is due to the fact its already phased as friendly vs not freindsly, but its hard to do anything here.
