From the looks of your video, your worldborder is not perfectly aligned to a block boundary, while the worldborder may not always visually line up perfectly with the edges of blocks, any blocks that it partially includes are treated as being within the worldborder. This means that you weren't actually pushing the blocks outside the worldborder.
I too have this problem, however my current location is NOT in a Germany speaking locale. I am located in the US and have tried clearing the cookies for the site, as well as the cache. This occurs on all computers in my house, regardless of which browser is used. So far, I have tested Opera and Chrome browsers. I have not yet tested if the same occurs at other locations.
What render distance were you using? If it's below 10, there's a good chance this is a duplicate of MC-2536.
IIRC, this is that minecart derail "feature" that was added awhile back that nobody really likes. It made it so that high momentum minecarts would fly off corners as an incentive to make people have slower minecart speeds.
This is intended. Torches don't react to 1 redstone-tick pulses and never have. They need at least 2 redstone-ticks to react.
This is intended. In what way would mixing concrete powder with lava make sense for turning it into concrete? When you get concrete mix from the hardware store, do you think that you have to drill a hole through the earth's crust to get lava to mix with it? No. You add water...
This is intended behavior. Collision boxes that intersect with itemframe hitboxes cause them to fall off.
You could just use a world download of an existing large scale flying machine like one of the more recent quarry designs that the technical community makes and remove the roof that they have, rather than building something yourself.
Previously, normal pistons when short pulsed would not cause the blocks they were pushing to be dropped immediately in the new position, the moving block would instead take as long as it normally would to arrive at its new location as if the piston had not been short pulsed. I don't know if the piston head itself immediately retracted though so can someone else weigh in on that part?
Yes, Cobblestone and Mossy Cobblestone walls.
JIRA seems to have mangled the NBT tag in the description. You'll have to remove the newlines if copying and pasting.
It seems that I was slightly wrong about the nature of the bug. It instead involves only boats summoned with multiple passengers. I will update the bug report to reflect this.
I just checked release 1.8.9, torches were able to be placed on the sides of redstone blocks back then and were probably always able to be as I seem to remember a lot of people using that behavior to start redstone contraptions that required a short pulse.
The ability to place torches on the sides of redstone blocks is very likely an intended feature. I can't necessarily say the same about observers although this behavior did appear in the 1.11 releases, but if anything, it's stranger that buttons and levers can't be attached to the sides and undersides of redstone blocks, observers and pistons than it is that torches can be placed on the sides of the first two.
I guess you didn't see my edit, I did add a list of blocks that they are currently attaching to that they should not be after some more experimentation.
As far as torches attaching to redstone blocks, I'd check some of the older versions to see if that might actually have been intended behavior. I'm pretty sure they always have been able to attach to them. If anything, I'm all for things being able to attach to more blocks, so long as it's consistent and makes some small amount of logical sense.
The vine behavior has not changed since 1.11.2. I didn't check prior versions but I assumed that was likely the intended behavior since they have to attach to leaves and other things. I also assumed that the difference in side attachment for torches and for redstone components might not be a bug because no one had mentioned it since we got observers and in all other aspects, components attached to observers the same as they did to pistons.
Ultimately that ties in with whether or not all blocks that "hang on" or attach to other blocks such as redstone components, ladders and torches should be able to attach to the sides and undersides of pistons and observers in the first place as they were not able to previously. That being said, components attaching to the tops of pistons was added so why not the sides and bottom as well?
I also find it strange that torches can be placed on the sides of observers but that other redstone components can not be and that redstone components can be placed on top of pistons and observers regardless of their orientation but not on the other sides when rotated differently but those details have precedence and may not be bugs.
This also applies to vines, buttons, levers and tripwire hooks. It also effects snapshot 17w17b. I'm afraid I don't know how to update the issue myself, so I can only comment here.
Confirmed for 19w42a. It also affects the UI, color now, tinting it blue and darkening it. Should I make a separate bug report for that?
