Full tutorial on replication + mob AI in game
https://youtu.be/kd6dOAJA9Vc

Short summary of issue:
-Piston with pushable Redstone block upwards will keep the piston extended regardless of any redstone signal connected to the base
-Mob AI is not able to find the path to a player if said player is seemingly floating in air (altho he is sneaking above the edge of an block - please view video - )
