Game sometimes removes the mine cart when logging out, and game crashes if you enter/leave mine carts to quickly.

The game crashes when use my mine cart elevator, i think its caused by entering the carts to fast, because the first car is fine, then then i spam click to go up, it crashes, and removes the cart when logging back in to the game, after the crash also it sometimes removes the cart if you re-load (not all the time, not 100% confirmed) so this makes mine cart elivators useless.

What i thought would happen:
I would go up the carts and out the top

What relly happend:
The game crashed after getting to the second/third cart afer spam clicking, and removed the cart when logging back in after the crash.
