There is a big bug about guild

Yesterday,I and my guild members can not chat,challenge and donate in the guild.This is a serious influence to us.We can not communicate and finish the quests.Our guild name is 墨雨晨曦.We need a proper settlement.

As a guild leader,I want to receive a fast and beneficial reply.One day later,more guild members run off.

Now guild system is recover,but I dont want to meet the same BUG
