Re-rolling Daily tour challenges

If I re-roll a daily tour challenge after completing it (i.e. I complete “get 30 kills” then I re-roll that completed challenge) do I lose the reward for the previous completion? Or does re-rolling a completed your challenge effectively make it so that you can do another challenge for that day?

you keep the reward. and you can keep re-rolling for more daily’s First one is free after that at the cost of iron.


Closing as the question has been answered.
