Some people were able to abuse a bug in our member editing page earlier today and add/remove members in some clans. We urge you all to check if your clan was affected by this. Check your member list and clan log for suspicious people being added lately or for people being removed from your clan. Here are instructions on what to do if this affected your clan.
If you still have clan leader access:
simply remove possible extra people in your clan and readd the people who were removed. Open a Cheat & Abuse ticket here
and tell about the case so the abuser can be punished.
If your clan was taken over:
Open a HelpDesk ticket here
and give the details and your clan will be fixed.
The bug has now been fixed so this shouldn't happen in the future. Adding and removing clan members was disabled temporarily while it was being fixed. Apologies for the inconvenience!
