When using a conditional chain command block after a repeating command block, the chain will seem to continue to run it's command even though the repeating command block is no longer outputting a true single to the chain. Don't know what is causing this, but the problem still seems to be happening. It seems like you can fix it if you reset them to conditional, but then it occurs again if they are ran again after being reset. While I am in a LAN world, this problem was still occurring before changing to LAN.
