Check the Dilithium Mining Bug thread just a bit further down the front page of this board. It's because you did the New Romulus radiation scan, this breaks the dilithium mining mini game. The only way to clear it is to exit the game, and then sign back in, or to remember to do dilithium mining first, before going to New Romulus. It's been happening since Season 7 was released.
