Rocket League on chests

I've seen that in many current chests prices that there is a Rocket League key to win, well in September 23th this game became free for everyone, so I'm concerned about getting that game if I want to open a chest, it isn't right to give a free game, is like giving nothing. I thought this would be already removed from there at this time. Is it going to be removed soon? What happens if I get to receive this key on the chests?

You can sell the reward.

Anyways, thanks for your suggestion and it has been sent to the team for consideration!
