Orange Fungia Question

[Tank Sinatra]

I have had this orange Fungia for just over a year and in the past few days it has developed a line radiating from its mouth all the way out to the outer diameter of it's disc. Has anyone else ever seen a plate coral have the line?

I'm not sure how they propagate. Anyone else in the R2R world ever have the one split?
