a comparator clock will not update a comparator except at the moment it is placed and the comparator will remain in a powered or unpowered state (depending on the signal it receives at the moment it is placed) unless another comparator is placed directly in front of it at which point it will update as normal but the last comparator in the chain will not update.
unlike the similar effect with repeaters which due to applying to the last repeater in a chain of 2 or more can be worked around by placing a block between the repeaters, this effect applies to even single comparators and is exclusive to 1.14
