I have a ship that I have built in Survial Mode. It has four levels, three of which have a single system of dispensers with redstone dust and redstone repeaters that i just put in. I placed five normal arrows in each dispenser and fired them using a lever on the top deck of the ship. The system has a charge all the way to the last dispenser but not all of them fired. There are a total of 144 dispensers in the system and only 28 of them fired. I was curious to know if anyone might know the issue or if there is a limitation to the number of dispensers that can be activated off a single switch.
The limit isn't the number of dispensers that can be activated by a single switch, its the number of dispensers that can be activated in the same gametick. If you stagger the repeater timings so that 28 or less fire at one time then they will all work.
