I have all the herbs because they are making stews but they don't recognize the orange herb. I keep putting a master doctor (and others)all around the flower but they won't study it. What do I need to do?

I found the orange herb has got a smaller drop zone then the others, maybe your screen settings are off a bit and its messed up the drop zone, but try dropping in different places around it and not just on it, and directly on it ,, if you cant get it to work send a technical issues message and one of the makers will help.

Make sure you watch the status screen, for the message to say, "(s)he sees a strange herb", before you drop.

Here is a map of where the herbs are located. Perhaps you are not at the orange herb.

LadyCFII's edit: This map is of a nearly completed village and contains many spoilers.

I didn't think about that, Borg, that may be the problem, too...

It amazes me what a large village that Village Monk has in that screenshot. I am so jealous.
