No answer, assuming no longer an issue.

Is this still a concern in the latest Minecraft version 14w08a? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Yes. I'm still able to reproduce the issue in 1.7.4. I'm not the issue reporter, so I can't update affected versions.

As described in my last comment and minecart-piston-collision.jpg, all minecarts, except the last one is pushed. If it's only one minecart, it's not pushed either.

There also seems to be a glitch where the derailing minecart is seems to be in the ground (one block to low), but the piston can still push them if it's not the last one. A queue of minecarts on a slope will constantly push eachother, but the last one is not pushed by another minecart.

I have some new info: See minecraft-piston-collision2.png. The piston will always push a minecart if the yellow block is removed. Even if it's only one minecart in the queue. Space issues might be a keyword here.

Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.7 or later? 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 is still an issue in both 1.5 and the 1.5.1 pre-release.

If you queue up a few minecarts like in minecraft-piston-collision.png and use the piston to push them one by one, the last one will not be pushed. There's no rail in front of the piston, that's on purpose. I still expect it to be pushable.

Also applies to pushing sideways.

Thimo, you've got my upvote. I would advise a little confidence in the team; they push out 10 or 20 bug fixes with each snapshot, and during times when they come close to release, when they focus more primarily on bug fixes and not on new features, they've historically put out on the order of 60 to 75 per snapshot. Get your issue voted for.

I gate this bug myself. Just noticed it yesterday in the latest snapshot.

Comment by Thimo Franken [ 07/Jan/13 ]

So is anyone going to do anything about it? Nathan?

Comment by Thimo Franken [ 07/Jan/13 ]

Thanks lol i didn't get it xD

Comment by Maarten Thijs [ 06/Jan/13 ]

yes it is a bug. and a very annoying one too, because of this bug cubehamster 14 story piston elevator no longer works!
but what Tails is trying to tell you is that you cannot look into the future to see if something is fixed there

Comment by Thimo Franken [ 06/Jan/13 ]

So is this a bug?

Comment by Tails [ 06/Jan/13 ]

You have to test it first before you can tell for sure.

Comment by Thimo Franken [ 06/Jan/13 ]

Sorry, but if it ain't getting fixed it is affected isn't it?

Comment by Tails [ 06/Jan/13 ]

Please do not mark unreleased versions as affected. You do not have access to this yet.
