People aren't explaining the problem well so here's my attempt.
With arrays, you can get Torque to take the most forgeted up variable names ever.
$Pref::Server::This[" is actually a valid variable with spaces in it! And punctuation too!"] = "<-- True";
This will work. You can see the variable's value, set it, and all that good stuff.
HOWEVER, when the server shuts down and exports everything called $Pref...
$Pref::Server::This is actually a valid variable with spaces in it! And punctuation too! = "<-- True";
As any coder will tell you, that is NOT a valid variable name.
What this means is that if you want to export data so that it's reloadable, your array names have to not contain characters other than the alphanumeric characters (letters + numbers) and the underscore/colon (_ and : respectively) or it won't work correctly.
