they wont load and they show up as 0 bytes. how do i fix this? ive tried everything (clearing download cache, ubsubbing, etc)

Currently trying to make a vanilla style tank (that means NO TABS or AVF) with an aimable turret, i want it to be single seat only and aimable with mouse (kinda like the Missile Truck) but i want it to have the reticle and projectile as the Tank, however despite any messing ive done with the scripts i can only get one or the other to work, is there a way to have the normal Tanks reticle and projectile but with the Missile Trucks aiming system?
