MC-107600Observer block causes bottom half of bed to break
While I was playing around with the new Observer block (or BUD block), I wanted to see what would happen when you slept in a bed. I placed down the Observer block (I have tried in all directions and the bug still occurs) and ran some redstone out of it. I placed down the bed, however the bed broke in half. The unusual part is that this only happens when there is redstone coming from the Observer block. This half part of bed is able to be used, you can sleep in it however if it gets updated then it will be destroyed. I hope this is fixed for the upcoming feature.
Thanks

[Mod] Neko;
Would it be better to reorganize this ticket along the lines of: "Block Updates cause bed and double plants to drop"?
Not to be confused with redstone updates, of course, as a redstone "BUD" switch doesn't appear to affect the bed/double plant at all.
This could, perhaps, help collapse this and the "relates to" tickets under one ticket.
Using a too-well-lit mushroom and a rose bush, for example:
Placing the rose bush causes an update to the surrounding blocks.
When the mushroom receives the update from the bush, it realizes that it is in an invalid position and drops.
When the mushroom drops, it causes an update to the surrounding blocks - including the base of the rose bush.
When the base of the rose bush receives the update from the mushroom, it realizes that it is in an invalid position as well (Because the top of the rose bush hasn't been generated yet) and drops.
Then, the top of the rose bush generates from the initial rose-bush placement.
If the Cactus block from MC-59303 is being updated, and updating, just like the mushroom from the above example, this could explain the behavior.
If the "Observer" block from MC-107600 is updating on game ticks, instead of redstone ticks, this could explain the behavior - and explain why redstone piston-based BUD switches don't cause the same issue, as redstone ticks, if I understand correctly, occur once every 2 game ticks.
Possible explanation for Observer BUD/Piston BUD differences:
- Observer BUD:
- Placing the foot of the bed updates the Observer block.
- The Observer block updates the foot of the bed, which realizes it is in an invalid position (as the head of the bed is missing) and drops.
- The head of the bed is placed.
- Piston BUD:
- Placing the foot of the bed updates the piston and schedules a "redstone tick".
- The head of the bed is placed.
- The piston extends - which, since the bed is already complete when it updates the bed, doesn't affect the bed.
Confirmed. See attached screenshot for reproduction setup. Place the bed with your cursor on the gold block so that the 2nd block of the bed ends up on the diamond block.
