Vehicles appearing in sp but not mp?? :S

[Net_Slayer]

I followed one of ghost's tuts on making a turret so i made a turret of my own. I also animated it there are no other problems... although when i put ghost's roller turret into a map for test it doesn't appear and neither did my own (i tested using create game>lan btw) anyway i then tried gong console and doing the map name thingy (u kno what i mean) and i see my turret and ghost's turret (strictly for test purposes ghost) i can enter ghost's turret but not enter my own no matter where i put the #gunner enter markers...



if any of the above problems could be answered please say so...
