An arrow glitch was created A LONG time ago, and nobody even noticed it. This glitch revolved around arrows being teleported to 0, 0. This glitch has very weird effects that may take effect on your contraptions around the machine. The machine's glitchy effects are only in the chunk that you put the machine in. Some of these weird effects in this chunk may include:

1. Entities can step on wooden buttons and power them. (also locks button)
2. Entities can also step on any preassure plate (not stone) and lock it.
3. Players can press buttons, which then locks them on press.
4. Entities may leave phantom arrows behind.
5. Players cannot place boats anywhere in the chunk.

NOTE: The dispenser must have an arrow in it.
NOTE: The miinecart has a standing button below it.
NOTE: The repeater is on it's default setting (1 tick)
