Crash

[traincrisis]

If you make a train with this rolling stock:
F C C C H H H R R R F
Where F stands for furnace minecart, C for chest minecart, H for hopper minecart and R for an regular empty minecart after launching this train minecraft will crash. Video for that: https://www.youtube.com/watch?v=7p4-DjhftRc
In crash log it says:

End of crash log

Edit: I saw that if you make an train longer than 6 carts it will crash (For example the train has 5 carts and 1 locomotive at front making 6 carts)
