Code:
PreCacheRaces()
        var/list/tempraces = dd_file2list("Data/Races.txt")
        sleep(30)
        for(var/X in tempraces)
            var/mob/Race/Y
            var/list/tempvars = params2list(dd_file2params("Data/Races/[X].txt"))
            //BEGIN DEBUG
            spawn(-1) world << dd_file2params("Data/Races/[X].txt")
            spawn(-1) world << params2list(dd_file2params("Data/Races/[X].txt"))
            for(var/bla in tempvars)
                world << tempvars["[bla]"]
                world << bla
            //END DEBUG
            for(var/Z in tempvars)
                if(Z)
                    Y.vars["[Z]"] << tempvars["[Z]"] //Line 56
            Races += Y
            //BEGIN DEBUG
            spawn (-1) world << "[Y] was added to Races."
            //END DEBUG
            if(Y.Limited)
                Limited["[Y]"] << Y.Limited
            if(Y.Extinct)
                Extinct += Y

runtime error: Cannot read null.vars
proc name: PreCacheRaces (/proc/PreCacheRaces)
source file: EX Races.dm,56
usr: null
src: null
call stack:
PreCacheRaces()
: New()

Any clues anyone?

I can post more information if needed.

It looks like you never actually set the value of your Race mob to an actual mob. Just defining the variable it defaults it to null, so therefore you cannot access its vars var.

            var/mob/Race/Y = new/mob/Race

The << operator is used to either output messages to a list, or write values to a savefile. As you are doing neither, you should not be using the << operator. Instead, you should be using the = operator.

Yeah, I realised that, but it doesn't actually solve the problem. >.<

EDIT: It did solve the problem, but it was caused elsewhere by the same mistake you pointed it.

Thanks ^.^
