So i was getting on tfm, checkin out the history log and found this.

[25/08/2015, 20:15] Pinkleafa has changed the rank of Orangmarshy to ","rang":".

Um, ive never made the rank rang before..

somebody else from your tribe might've replaced your desired rank with "rang" instead

try checking ur rank list

It's also possible the rank ID didn't load properly, given that rank in French is "rang."
