The Chainsmokers had a great show with a not so great ending.
While performing in Pittsburgh, the Chainsmokers thanked their fans with a lighted up sign saying "Thank You Pittsburg."
The group then went to twitter to lighten up the mood by tweeting out a new edited sign with an added 'h' at the end.
They also shared with the public saying that they're "totally putting their visual guy on blast."
