For those of you not keeping track, due to engine changes TF2 doesn't work properly on SourceMod 1.4.3 regardless of the gamedata. You
will need 1.4.4 snapshot 3510 or higher (3514 is the latest at this time).
Also, TFItems and SDKHooks both had updated GameData. I know TF2Items gamedata is in the Updater. If SDKHooks isn't, you can
manually download the latest version of engine.ep2v.txt and put it in addons/sourcemod/gamedata/sdkhooks.games/
