howcome

when i put in a new model into my gohan folder it said this when i tried to play a game it exited out to the desktop and a window came up saying Mod_NumForName: Models/players/ssjgohan/ssjgohan.mdl not found

howcome in experimental mode, version 1.2.3 the dragonballs arent there in any stage? team and free fighting mode are fine but experimental mode does not work, in the old esf the dragonballs worked, is there a patch for 1.2.3? for the dballs?
