Two bugs - minecart and femur bone for the dog

[Default Option]

* The empty minecart must be pushed by a character and then the character must jump into the moving cart.. or the trigger for the minecart switch won't be shown and the minecart cycle will just loop (eg: if another character pushes the minecart with a player in it).

* After blowing up the explosives and draining the water.. there was no femur bone ANYWHERE on the map to trigger the dog. I reloaded the game and the bone was found in it's default location.
