Minor bug: The mission was posted on the pre-matchmaking screen was in German.
Major/Gameplay bug: The teleport ability has the potential to fail upon use (presumably because the player is teleporting to a position that another player has just moved to. Once the teleport ability fails, the cooldown does not start, and will not recharge until the user has died and respawned.
Thanks for posting your concerns. Both of your issues are fixed in the latest build. Thanks again!
