 Description   

When you take a mine cart ride and fall onto a mine cart track while flying over a solid block before said track (yet still landing on the track without touching the solid block ever) you will take fall damage later in the ride, often after you fall a distance again to another track (without touching solid blocks) or when you near the end of the current track. Evidence can be found in Hat Films' Epic Hatventure:

It's been around since before 1.1. Similar bugs:

The x is broken.(If 'blocks' is1 1 1, x,y,z is 0 1 1)
and When I use 'kill' my skin become steve.
Also, when I broke the tall(2blocks)plants's bottom, it's skin change to sunflower and return to original plant's skin in short time.

This is caused by server-side or client-side lag. Should allocate more ram to fix.

Aha, thanks for the video clip and test world. It's fixed now

X = -97.4
Y = 69
Z = 172.1

for the start of the minecart track to test.

Problem being that this bug doesn't have any relation to lag client or server side in terms of network activity. Here's a video with JUST the issue:

Make sure to watch the whole thing, as the first fall will not do damage. Subsequent falls WILL however BEFORE you actually fall with the Minecart. (Added a world download to the video.)

It happens from 10:50 to 13:40. Note that they die before their minecarts ever land. I can also make you a small map that has it without lava as to not confuse it with the other bug.

Don't link to a 20-minute video clip without telling us when in the clip the bug occurs.
