I had some dialogue is was reporting as profane and I couldn't for the life of me figure out which word it didn't like. I had to start randomly pulling words out. The culprit? "Hard". What?!
My quest only shows up if you search in the "best" search, and it's only a non-submitted quest. I saw it once in the review section but now I can't find it. Also, I got one comment on it which I can see in foundry but not in-game. There's just a lot screwy with the listings...
There are definitely single mob encounters, I've used them. You'll need to look a the descriptions of each encounter to see. I've never tried it, but I wonder if you place an encounter it will allow you to remove individual mobs on the detail screen, much like it lets you reskin individual mobs.
