| Description |
|
I was building a piston-based mob farm (in the Nether), and I found that three of the blocks that I had in front of sticky pistons had disappeared. When I investigated more closely, they were still there, only they were invisible and indestructible by any normal means. I think these are block 36, and when I right-click them, they disappear. I've seen other bugs talking about this ( I do not have a recipe for reproducing this. This is with a mostly vanilla Minecraft, I'm not running any "mods" and the ONLY thing I've changed is the LWJGL library (to v2.9.0 to avoid sticky key problems). I'll try to make a copy of my world downloadable, but it's more than 10M, so I can't just make it a normal attachment. |

I found a way to reproduce this while working on solving another bug ( https://bugs.mojang.com/browse/MC-12799 ) Copy of post with replication from https://bugs.mojang.com/browse/MC-12799 : Replicated again. Screenshot information:
laggtest.rar is the world download to replicate this yourself. Edit: Used 1.7.10 to do this test. |

I can confirm this both in 1.7.8 and in 1.7.10. The spot where the piston was supposed to be is empty, all you can see is the outline of a block that is a bit of from the position where the piston were before. You can not destroy this invisible block with any tool. Right now I have 4 holes like this that I just noticed in my whitch farm. The previous ones I mannaged to solve to get back somehow (dont remember how). The original pistons (that are now gone) were moving fast back and forth fast when triggered. This is observed in multiplayer. I have also observed pistons get stuck while both beeing pushed out and retracted at the same time when using a piston/hopper clock. (Dont know if its related) Those pistons are possible to destroy and place again to fix it. (The invissible ones aren't) |

Resolving for now. |

I have not been able to reproduce this, possibly because I don't have a good recipe to reproduce. I'm not convinced that it's actually fixed, but at the same time, I have no evidence that it still exists in a recent snapshot. It should probably be closed, but I don't understand how to change the status myself (if that's even possible). |

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

Argh, apparently file-dropper.com deleted the file. It is only supposed to delete it if it has not been downloaded in 30 days, and it's been less than that. Anyway, so I don't have a backup of that world, and I already destroyed the blocks by right-clicking them. |

FYI, the link doesn't work. Is there another way that you can find out what the invisible block is? |

Here's a copy of the Nether portion of my world. I only included the Nether portion to reduce the size of the download. Add this to any existing world, go to the Nether and go to the coordinates on the screenshot and you'll see the invisible blocks. |

You can link to, say, a dropbox download link if you wish to upload the world. |
