Whenever I equip Wonky the Donkey, my waterworks cape flows through my wizard rather than behind it. Un-equpping the mount does not correct the graphical bug. The bug remains until I exit the game without Wonky equipped and enter it again, but as soon as I equip him again, the bug reappears.
The bug occurs in outdoor areas and not in indoor areas. Removing the mount and going into an indoor location also fixes the bug, but equipping the mount again will cause the bug to reappear.
I'm glad the issue has received attention, but I'd really like to be able to have my hilarious mount and still be able to wear my capes properly. I did pony up the cash for it, after all (pun totally intended!).
Thanks for the information. It's good to know people are on the case and that you actually take time out to respond. Good business has good customer support.
