Chell player model error with point shop?

It was working perfectly fine yesterday but today it became an error and I checked single player and it wasn’t an error there. Here’s the setup for Chell in pointshop. (According to my friend GMOD Tower’s Chell is screwed up too.)
ITEM.Name = ‘Chell’
ITEM.Price = 10000
ITEM.Model = ‘models/player/chell.mdl’
ITEM.AllowedUserGroups = { “admin”, “staff”, “owner”, “superadmin”, “butt buddies”, “ultraadmin”, “member”, “trusted”, “intern”, “drewdinie”, “coder”, “vip”, “moderator”, }

function ITEM:OnEquip(ply, modifications)
if not ply._OldModel then
ply._OldModel = ply:GetModel()
end

timer.Simple(1, function() ply:SetModel(self.Model) end)

end

function ITEM:OnHolster(ply)
if ply._OldModel then
ply:SetModel(ply._OldModel)
end
end

Fixed in next update, when opimizing Portal 2 Chell, Max accidentally deleted the Portal 1 Chell. He also moved Portal 2 Chell to the wrong place.

So basically, just wait 'til the next update.

Ah. Thanks. The people on my server were complaining about it but I figured it was a pointshop issue.
