I'm playing Minecraft: Java Edition version 1.11 on PC. I was designing a flying machine with observers and pistons when I observed this bug.

Whenever the flying machine sets off, it creates randomly, some observers and pistons, throughout its path. These components can be broken but will not drop as an item.

Is this problem related to some issues in chunk loading/refreshing?

Reloading the save removes all these randomly created components.

I've uploaded some screenshots of these instances

Is there a solution to fix this issue?

  • Why are you in 1.11? – Fabian Röling Jul 18 '19 at 15:15
  • The reason I'm playing 1.11 is because I'm not getting a decent fps on the current version. – SlayerDiAngelo Jul 18 '19 at 15:17
  • Try 1.12.2, it has better performance than 1.13 and 1.14 and might already contain a fix for this. – Fabian Röling Jul 18 '19 at 15:18
  • I'll try it, aren't there any official patches or fix? – SlayerDiAngelo Jul 18 '19 at 15:29

    You mean bug fixes applied retroactively to past versions? No, that's what new versions are for. – Fabian Röling Jul 18 '19 at 20:26

These aren't actual blocks, these are only visual bugs, so-called "ghost blocks". To test, you can for example try to place a block on them and you'll see that it instead places the block where the ghost block was. A lot of bugs that caused ghost blocks were fixed since 1.11, so I recommended playing a more recent version.
