char_id is the primary key for the guild_members table. There should be no way MySQL will allow duplicate entries:

mysql> describe guild_members;

| public_note    | text                  | NO   |     | NULL    |       |
| alt            | tinyint(3) unsigned   | NO   |     | 0       |       |
+----------------+-----------------------+------+-----+---------+-------+

mysql> insert into guild_members(`char_id`) values(1234);
Query OK, 1 row affected, 1 warning (0.00 sec)

mysql> insert into guild_members(`char_id`) values(1234);
ERROR 1062 (23000): Duplicate entry '1234' for key 1

EDIT: Must be something to do with changes required for bots. I see this in bots.sql

ALTER TABLE `guild_members` DROP PRIMARY KEY;
