Ive noticed the same. Built an automatic farm based off tangoteks recent design, had noticed that the sugar cane doesnt grow. I manually placed and noticed that it glitches before you can place another one on top of it. I don't know if its a hit box collision from the pistons. I tore it down and tried another design these are not zero tick farms and they wont grow infront of observers. Tried in a single player world same issue.
The issues with the spawners have been fixed when I resynced the world. Mob grinders dont work neither do my gaurdian farms. No spawns. I have resynced and rebuilt this world a load of times with no success on the mob grinder or gaurdian farms.
