User blog:TheRay1993/Bug in Guild Recruiting

I'm an officer in my guild. For quite sometimes when I'm trying to send a guild invitation to other players via ID search, the system said "you already sent an invitation to this player" eventhough I haven't sent any. Some of our officers seem to have the same problem too, making the recruiting difficult since only the no-problem officers can do the recruiting. I've reinstalled BF 3 times, and even report the problem to the support center but none works. Anyone has a solution to fix this?
