[MC-55635] Comparator clock not activating command blocks

See the attached image. The comparator clock is working, but only the command block on the left is getting triggered. (/say hi)

Steps to duplicate: Build the same structure you see here. Make sure there is only 1 redstone dust between the clock and the (faulty) command block.

I have noticed that command blocks must be 2 or more blocks away from the clock for them to work.

Oh, and there is an error message that says "unknown command..." in the command block on the right but the console command in the block is "/say hi"

Also... I believe this bug has been in the game ever since comparators were introduced... but I didn't want to type every version above.

Playtested this in 14w21b (with 2 different messages instead of the same message in both). I put "/say bye" in the right one and got "hi" "bye" "hi" "hi" "hi" "hi" "hi" "hi" "hi" "hi" "hi" "hi" as a result, so bug basically confirmed. The right one fires only once.

yep makes sense, because the command block gets powered when you turn the clock on, but is constantly receiving one signal instead of pulses.

Was able to confirm using the setup in the picture.

This works as intended. The redstone that is attached to the command block on the right is not ever at signal strength 0, but rather is switching between 1 and 14, which is intended behavior. Therefore the command will only be powered once. You can see this for yourself by pressing F3 and looking at the blockStates on the right side of the screen.

Edited for typo.

Oh that makes so much sense! Thanks Avstar98
