Suspected as much, though it may have been nice to have a standard. Didn't even know the nurse needed a formula until last night. Way to go on developing new content!

It's not listed on the wiki, either.
May I suggest that minor quests like this be kept off the wiki. Here is why, it is nice to be surprised with minor side quests in game. Especially more so if the side quests do not have any real discernible influx onto the larger or main quests. For example you don't need to do some off the wall and out of sight, side minor quest to attain "The Holy Item" of "Advanced Hero Quest for World Peace". But little side quests just for the sake of being minor quests, giving new and fresh adventures, are nice.
And keeping them off the wiki sort of provides them as gifts. They offer 'fresh and new' content, which is really really nice. "Oh look a quest, gee stumbled over that one!

" Overall as far as world building is concerned, it helps too. Players are further encouraged to explore, the world expands and fleshes out. Perhaps, later I may have ideas for quests.
*still wants a land rover to use in Mana World, imagines the look in the eyes of evil mushrooms as he mows them down in said rover, goes Muhahahaha!*
