The bug:
Command block telling me it has a syntax error when it worked.
What I expected:
For the syntax to not read as an error.
What happened:
Building a randomizer with armor stands sending a Redstone block to a random stand, the command block sending the Redstone block to the armor stand works everytime even though the syntax says there was an error.
To recreate:
Build a randomizer to send a Redstone block to an armor stand which activates another command block removing the Redstone block as well as another command block to clone a chest. (see image)
