Hammer doesn't compile maps properly

[Flatterbuckle7]

I've been trying to compile a map called e3_town, and so far i've been trying to compile it but for some reason every time i attempt to compile it, there's always something missing in the level. For one part of the level there's supposed to be a lever that activates a cart thats supposed to take you somewhere, but for some reason the lever to activate the cart was there but the cart is completely missing from the map in-game and was only visible in hammer. The second time i compiled the map, the lever and the cart were completely missing in-game. What am i doing wrong? (I think this version of the map was from the "Randy" folder of the WC mappack)

To fix this, you'll need to change the props to override variants. ie prop_physics (the minecart props) to prop_physics_override or prop_dynamic (the lever) to prop_dynamic_override, etc.
