Affects Version/s: Minecraft 1.8-pre2, Minecraft 1.8.1, Minecraft 1.11
Fix Version/s: None
Environment:Windows 10 Pro Build 14393.447
Intel Core M-5Y10c @.8GHz * 2 cores * 2 logical processors
Intel HD Graphics 5300
Java version (System): 1.8.0_112
Java version (Minecraft): 1.8.0_25
Steps to reproduce
1. Place any block with tile entity (Chest, Furnace, Command block, etc)
2. Place attachable blocks like ladder, button, torch, etc (or setup a BUD switch)
3. Delete the block with tile entity using the command /setblock x y z air [0 replace] (x y z being coordinate of the block)
4. The command output (or chat screen) says "The block couldn't be placed" but block gets deleted anyways, and adjacent blocks are not updated at all. (for example, a BUD switch would not activate).
Note : This only happens specifically with setblock air replace.
