My clan is having an issue with our clan tag... we currently aquired level 30 clan status and the leader tried to change to the new blue and red title.

When he did this it is now telling him that "cannot add clan tags because of prohibited text", the clan tag has been the same since the game was released ..  >30<.. he was allowed to change it when the clan reached level 15 with no problem. Now all of a sudden the clan tag is prohibited. We have been established with this clan tag and voted we are not going to change it. Our clan is 1200+ including the PS3 side, we currently have 6 elite clans, and this is the first time we have had this kind of problem. We as paying elite members of this clan would like this matter to be dealt with. Thank you very much for your time.
