Command Block Effectiveness Range
Can you be too far away for a command block to work? (ie. command does not execute)
I am curious because I was making a super-flat world a void one by filling a 7x7x4 zone around the player with air to clear it. But as I got farther away from the repeating command block, the space around me was not being filled. However when I got close enough to the command block, the command executed successfully. There is no radius limiter in the command itself, so I was wondering wether or not there is a hard-coded range limiter for command blocks.
