Minecart disappears from tracks

Never experienced that issue.
(Except when some mob jumped into the minecart and other mob pushed it onto a powered rail, but the minecart was parked on the other end of the track with a lonely skeleton)
Can you please attach a screenshot of the endpoint ?
And please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

Minecart sitting on powered down track. The powered section it two blocks long. To the left and right there are powered up sections, so when I need to go I just jump in and push it onto one of the powered up sections.

Crash report.

Is there any chance that the minecart got pushed my a mob onto the powered rail ? (assumine not, since peaceful, but maybe there are some golems running around ?)

If you break a couple rails in front of and behind the place where the cart stops, is it there when you return?

I do not have any Golems or other mobs running around in the mine.

I will try breaking the rails on both sides next time I am down there, but that will be a few days to go.

It seems that breaking the rails, stops the cart from disappearing. Strange...

Except for then the cart cannot be bumped onto a powered rail (which should not happen because there are nobody but me around to bump it and then I would just find it at the end of the rail, which I dont) why would breaking the tracks stop the cart from disapearing?

Happened again. Took the train up to my 'hold'. Got of and logged out. When I logged in this morning, the cart was gone. Follow the track all the way to where the cart should have ended up if it was bumped, no cart to be found.

I upgraded to v1.51 yesterday, but this happend after the upgrade.

I include a screenshot of the endpoint where the cart was parked.

I experience a slightly different yet similar situation with hopperminecarts. I use hopperminecarts as vacuumcleaners beneath a mobtrap, but when I go a good distance away from my base (probably beyond my base being loaded) and return, my hoppercarts are gone. The mobtrap is one based on killing mobs by falldamage so mobs on the loose or some other interaction with anything other than me isn't the case.

I still have this problem in 1.6.2 and more frequent now. I think it can have something to do with leaving the cart when it's not centered in one block. My track have two stops at the beginning it have a slope sometimes the cart stops half way up so it's between two rails. At the end it's a powered rail next to a solid block here the minecart sometimes goes a bit in to the wall. I've had the cart disappearing from both stops and since it's a short track I've checked the hole track. The carts are simply removed, probably since the game don't now how to handle their placement.

This just happened to me, or I just noticed it rather, it could have happened anytime in the last 40 minutes. I'm on minecraft 1.6.4, and have a 1000 meter track built at level 10. It's been fine for several weeks, but last night I logged off with the minecart sitting against a stone brick wall on an unpowered booster rail, and when I went to ride it today it was gone.

Dude! Where's my cart?? 😉

Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

This ticket is incomplete without the requested information, no response has been received within a reasonable time and we are assuming the issue has been resolved. Should your issue return please submit a new complete ticket with all available information.
Please review the guidelines before reporting issues.

I can confirm: it is still a bug in the most recent versions of the snapshot/launcher.

In my case, the following happens:

1.) Leave a minecart ON A TRACK on the Nether. It is completely stopped, on an inactive power rail.
2.) Leave the Nether.
3.) Log off/quit the game/unload world at some point.
4.) Come back and it's completely gone. Not dropped, not at the other end of the rail, just gone like it never existed.

This only seems to happen to the last cart I rode in; at my "Nether station", my other minecarts appear untouched.

This has been a problem for a while and it's getting really, really annoying.

Which version have you tested it in last?

14w04b, with launcher 1.3.9. Windows version.

Still an issue, Mac version 1.8 with Launcher 1.53.

Cart left on a unpowered power rail, disappeared. It's happened to me twice (once in an earlier version and again today). Both times, cart was left on an unpowered power rail. I have never seen it happen on a regular rail but I do tend to park them on unpowered power rails so can't say for certain. I walked the complete rail and no cart anywhere on it (so it wasn't moved by mob). Only seems to have happened in the last mine cart I used. (Carts other than the last one I used that were 'missing' have always been located as having been moved by mobs.)

It does not happen every time I leave a cart on an unpowered power rail and logoff.

This has happened to me in the standard world (haven't seen or tried it in nether)

The setup in which I park my mine carts and which they sometimes disappear from is:

Stone slab - unpowered power rail (where cart is parked) - normal rail - powered power rail - rest of track…

On a last note, I think but am not sure, that when I logged off both times the cart disappeared, I was significantly far away from the parked cart (multiple chunks away).

====
UPDATE:
Distance is not a factor, I have had two more carts disappear in the last week, one when I logged off just 20 blocks from the cart.

This still happens in 1.8.1. It's kinda strange though. On my server I have 2 identical farm setups, with a hopper-minecart collecting stuff.

In one of them, I have to replace the minecart at least twice per week, and in the other, I never had to replace it, not even once. It's been running for months without any issues.

The only difference between the setups is the orientation. The disappearing one has the unpowered power-rail oriented east-west, while the functioning one is oriented north-south.

I hope this helps! 🙂

EDIT: I forgot to mention, sometimes, instead of disappearing, the hopper-minecart duplicates, including inventory. So I end up with 2 minecarts clashing with each other. One day after I logged in, there were 5 minecarts in the farm!

I can confirm this happened to me as well playing minecraft server 1.8.1. I left a minecart sitting on an unpowered rail that is part of a launcher system. It consists of an unpowered rail, normal rail, and then 3 powered rails. The unpowered rail is connected to redstone and a button. Pressing the button launches the minecart. I logged out of the game and then upon return , the minecart was missing. The map is set to peaceful so there is no chance that a mob destroyed it. Given that a minecart costs 5 iron ingots, it is sadly missed.

Is this still happening?

Ticket resolved as incomplete, because no answer in a reasonable amount of time (1+ year), if it still happens, please update the ticket.

Windows 10 Edition, newest update (1.2.552.0)

This project is for Java edition issues; MCPE is its own project.

This has happened to me a few times in the past couple days. I have a closed loop rail system, there is no where for the carts to wander off to, they jsut go in circles. They are not stopped on the system anywhere, they are just gone.

In this case they are specifically chest minecarts.
