when you exit a vehicle the keybinds bug out and lets say you change your main action bar (1) to the second one (2) while having every other default action bar activated and scattered across the screen it will use some random bar not even attatched to the keybind  making it hard to press the button the second action bar since he clearly wont be aviable untill you /reload. as a vehicle exit count normal vehicles aswell as demon hunter rain from above pvp ability.
