Error with AppleJack. - MySQL Tables we think.

[Borris_Squad]

So my developer is lost, and he does not have a facepunch account, so he asked me to post this.

He is getting this error

  [ERROR] gamemodes/applejack/gamemode/metatables/sv_player.lua:654: attempt to concatenate field 'MySQL Table' (a nil value)
