Observers can cause blocks to be stuck in the powered state when being pushed by pistons

      If an observer block is pushed by a piston at the same time as it is sends a redstone signal, the block it would power after being pushed is stuck in the powered state until it gets a block update. If you build the structure in the first screenshot, and then place a upward facing observer on top of the redstone, the block on the right will stay powered. Also, if you build the structure in the fourth screenshot, the block below won't be powered when the observer updates until you give it a block update.
