Bukkit

What steps will reproduce the problem?
1. Start a track
2. Attempt to climb a block, stairs, slabs, stacked snow
3.

What is the expected output? What do you see instead?

I expect it to act as ucars is. It climbs blocks, stairs, etc. Instead, it just stops. It kind of climbs when you go on the side... but not really

What version of the product are you using?

Latest version. I'm running spigot 1.8.3. Ucars works as it should, mario kart isn't

Do you have an error log of what happened?

No errors

Please provide any additional information below.

You literally cannot climb anything.
