Darkness not a domain of Mask

[sharkinajar]

Hi,
I'm making a Mask cleric that has the domains Darkness and Trickery, yet I get the error that it is not a valid combination. On the statue stating the combination, it says it is allowed as a domain for Mask. The forums state that both Darkness and Trickery are attributed to Mask.

On the forums, it says:

Mask

Master of All Thieves, Lord of Shadows
Symbol: Black velvet mask tinged with red
Home Plane: Plane of Shadow
Alignment: Neutral Evil
Portfolio: Shadows, thievery, thieves
Worshipers: Assassins, beggars, criminals, rogues, shades, shadowdancers
Favored Weapon: "Stealthwhisper" (longsword)

Cleric Alignments: CE, LE, NE
NwN Domains: Darkness, Evil, Trickery, Luck

Nevermind, apparently it decided to switch me to portal, or I misclicked.
