I made an intro for a map I'm currently working on, and the once I updated Minecraft, half of the commands no longer work. I have to set a block to redstone beside the trail of redstone wires for the teleporting commands to work. All the other commands work fine like /effect and /title. Some commands only work with a pulse and others, such as /tp need a constant redstone input, like a redstone block. I'm assuming this is a bug because all of my command blocks worked completely fine before the update. I'm using the intro as an example, but all the commands in my map don't work properly.
