SpartanUI & Bartender4 bug the screen shot is from another quest that can have the bug called (flight in firelands)
SpartanUI Version: 4.4.3
Bartender4 version: 4.7.7
Zone: Mount Hyjal
Quest: The Bears Up There (actually got stuck in the tree and could not move)
Bug: Bartender4's Use Blizzard vehicle UI option does not work or is broken and not loading as despite the option being checked the vehicle ui bar does not show or is not being displayed its now just empty space others have reported the issue as well not just with this quest but in other quests or areas. I also tried to report the bug to the developer of bartender but I don't have an existing wowace account and to top it off the sites modules are disabled preventing you from creating a new account. This bug seems to be deeply rooted in history after reading many posts it would seem the same bug with the vehicleUI not showing goes back past even 2011 at different points in time
Temporary workaround: use the command /console reloadui then after finishing the quest or getting out of the vehicle use /console reloadui again to reset the position of your bars and minimap.
