Thank you for commenting. But besides ent_remove, what could it be than?

I have in the action gun_client_missile (called by the line: ent_createlocal("MDL_MissileLaser.mdl",vector(my.x,my.y,my.z),gun_client_missile);), a few 'you's'. Could that be it, even though the error is refering to the action gun_laser_missile?
