While mounting K-drive, instead fall through the grid into perpetual freefall.

[(PSN)tomolandry]

More and more often, while running bounties in Fields of Eidolon or Fortuna, mounting the K-drive causes the warframe to slip through the grid and keep falling indefinitely not being able to move or do anything and the only choice is to either abort mission, leave squad or reboot the game/console. In all cases the bounty is forfeight and all earnings are lost.
