I'm pretty sure its because for the conditions:
Code:
[vehicleui] 12; [overridebar] 14
only causes the OverrideActionBar buttons to be updated where the other conditions:
Code:
[possessbar] [@vehicle, exists] 12; [shapeshift] 13; [bar:2] 2; [bar:3] 3; [bar:4] 4; [bar:5] 5; [bar:6] 6; [bonusbar:1] 7; [bonusbar:2] 8; [bonusbar:3] 9; [bonusbar:4] 10; [bonusbar:5] 11; 1
update the normal action buttons.
After work I'll dig through Blizzard's code to see if there is work around to get one bar to handle both, otherwise I'll clean up your new vehicle bar code and make it work without the event part.
