Could you post a screenshot of the medal?

If I see it again, I will.  I only had it for about a day, and with only 5 of them on a server, I don't see it often.

I just want to make sure, is it the shape of a scythe? Could it be farming? The farming medal doesn't look like a sprout like the actual icon for farming, so i'm wondering if it could be that!

No, I don't think it's a scythe, and as I only rank 14th in farming on my server, I doubt I'd be #2 for most of a day.  It looks like this, only light blue and facing the other way.

Got a screenshot!  Notice that the odd medal is to the right of the barter medal, implying that it is something to the right of barter in the medals list.

At the time of this screenshot, I was ranked 18th in farming, 16th in wealth (to the right of barter) and unranked with a grade of A (but just below #30 who had 61.06 with a level of 61.04) in growth.  So, I don't know what I was ranked 3rd in.

Thats the RBF ranking icon. If youre on a channel where basically no one has an RBF score (as it happens often on Olvia and Season servers, since RBF rankings are per character), anyone can be chosen at random to get the higher rankings. 

If you check in the ranking list, you actually have to click on the RBF kill ranking (its the one on the right corner), as the ranking itself doesnt show up in the left column (has been a bug forever, basically).
