How so? Does it:


 * slide out of the truck, or


 * does it just pop out of the truck?

If it does on the 1st situation, you may not be stacking it properly. If the strategy isn't clear enough, reply so I can try putting more detail.

If it does on the 2nd situation, like on the picture on the right, you're either suffering with bad internet or with a server containing huge bases.
