Hooks not called on new clients?

[blastehh]

I've been testing texthat and noticed that if an existing player is wearing a text hat, any new player that joins the server will not see the hat until that player re-equips/modifies the hat.

Are hooks not getting created/called for players that join afterwards?

for reference, texthat uses function ITEM:PostPlayerDraw(ply, modifications, ply2)
