Sustained difficulty!

You can set your opinion on sustained difficulty in My Submissions -> View Details as with map difficulty. Personal opinions DO count for this.

also grey dots for personal opinions now show. red dots indicate sustained difficulty was intended. this is also shown by the red up arrow in the table.

If you have cleared Mature Grape or The Road to Purgation, you will need to set a new opinion for [C] (and potentially [FC]) since they were split, and its ambiguous as to which you were referring to. (sorry) enjoy!
