Bug Explanation:

While I was creating a system for exchanging for chests, I noticed that the command "/ clone" in the Command Block works, but the command block itself was not identified. And that made the Command Block not pass its success to the other Command Blocks that were also in jail and conditional.

How to perform:
To perform it is necessary 3 Command Blocks, one in Repeat and Always Active mode, and the other two in Chain, Conditional and Always Active mode. The first Command Block can have any command, the second will have the "/ clone" and the third will have a command like "/ give" or "/ effect", the Command Blocks are positioned as one of the added images, being from left to right. After executing the command of the first Command Block, the second will be activated and the third will not be activated due to the Bug.
