I have a world (superflat, creative) that has a row of teleporting command blocks, each block with a pressure plate, teleporting you to the next command block, which repeats until the end. First pressure plate you hit turns off Command Block Output gamerule, then at the end a command block turns it back on. But the problem is, the teleportaion doesn't always work (in the screenshot it shows the problem, if you can see it). If you need more details comment, or for a faster response email me at burkedominic7@gmail.com (update - email doesnt work)
