Here is a link to a short video showing my problem: http://youtu.be/SmdJx3kaHTk

Notice in the video how the first cart drops into the grass block after derailing, while the second cart stays above. I have Minecart Collisions set to false in the config, but shouldn't that affect carts I place as well?

When I use a diamond block to spawn a cart, then I use a platform sign or a lime wool block, the player is pulled into the cart 1 block below the normal level. If I place a cart from my inventory onto the track and then use the platform, it works normally. I have checked the config, and I didn't find anything which I thought would cause this.

What steps will reproduce the problem?
1. Use a diamond block to spawn a cart
2. Have the cart roll over a platform

What is the expected output? What do you see instead?
I should be placed in the cart with my feet at the cart level. I am placed in the cart with my head at cart level and my feet in the block below. I cart still moves with me in it, however.

What version of the product are you using?
2.3.1

Do you have an error log of what happened?
No. I will turn on debug logging and see what I find. I will repost with an update. I will also check to see if this happens with spawn signs rather than diamond blocks.

For some reason I can't get spawn signs to work...

I tried this(http://i.imgur.com/hbUjGfN.jpg) to see if the cart was trying to spawn in the diamond block instead of on the track above it. If that were true, the cart should fall onto the lower track and then act normal. However, the same problem occurred when I entered the cart on the lower track.

Here's the debug log:

I press the button

The cart rolls over the change speed sign (so it doesn't fly forward when dropping)
