Races not working

[draikonm]

When trying to set a player's race, exceptions are thrown to the console.

Races do seem to work if you edit them into the skills.csv, for example:
1,"Pickaxe Use",4,16,2304,0,0,0,0,0,0,257,"Highlord Dwarf Scavenger"
Would allow only the Highlord, Dwarf and Scavenger race to train in that skill.
You must manually set the player's race in the DwarfCraft.db, so the error is just with the /race command itself.
