Harry Shearer seems to have announced that he will no longer be working on The Simpsons.

In a series of tweets, the voice of loved (or hated) characters such as Ned Flanders, Mr. Burns, Principal Skinner, and Waylon Smithers, indicated that the show would be moving on without him.

James L. Brooks is the show’s producer. Creator Matt Groening and executive producer Al Jean confirmed the news, releasing the following statement, according to Variety:

Harry Shearer was offered the same deal the rest of the cast accepted, and passed. The show will go on and we wish him well. Maggie took it hard.

They also announced that the characters would be recast, rather than killed off or written out of the show. Shearer also voiced the characters of Kent Brockman, Reverend Lovejoy, Dr. Hibbert, Scratchy, and Lenny Leonard.

It’s not the first time that contract negotiations have caused drama for the show. In 2011, the entire cast threatened to quit over a proposed pay cut by Fox Television. They eventually did reach a deal, with both sides compromising on their original demands.

The show has run for 26 seasons, and was renewed for a 27th and 28th season in May of 2015.
