Changed Summary:
Minecraft Observer Block detects non-existing UpdatesMinecraft Observer Block does not update itself correctly
Changed Description:
Forming a ring of Observerblocks with
one cornerchanged to a piston head of an upwards facing pistoncauses the Observer blocks to give out a constant signal.This might be intended, as the piston is recieving "BUD"-power from one Observer block and the retraction of the piston once the signal ends should cause another blockupdate.
However, by removing the piston this cycle should end. Asseen in the pictures, this is not the case.To reproduce simply copy what you see on the picture.

Another formation where it stays powered:

I don't know if it is for the same reason, since in my design I think they should not update each other at all...
Maybe because it would fit in multiple tabs...
It's called BUD-power and as far as I know it will stay in the Java edition because of its usefulness for the redstone community.
I managed to get entities that were standing on top of a shulker box stuck inside it by giving for example a zombie a 2 high space, collapsing it to 1.5m by opening the box and with the chest open, pushing the zombie down using a piston.
The zombie was unable to move below the pistonhead. Even if I gave him a target he did not do anything until I removed the piston.
This allowed the zombie to free itself by getting displaced as described in your report.
