Actually, the problem is that the guild coloumn only allows 25 characters in the default database (anyone happen to know the real limit on guild names lenght?)
Antrim is a member of "Preservers of the Predators"
Thats a 27 character long name, hence the error.
The solution is to increase the size of the coloumn.
ALTER TABLE 'members' CHANGE 'guild' 'guild' VARCHAR(35)
Alternatively, if you are just setting the bot up and it does not yet contain any data in the database, start with a fresh one after making the following change in Rooster_RAID:
guild VARCHAR(25),
Change to:
guild VARCHAR(35),
