      Description

      When loading chunks that previously had command blocks in them, the command blocks will be there, however the command inside will be lost. Below I have the error log the server provides for each command block loaded.

      I should also mention it is not command specific, due to the large amount of command blocks I had, and how none of them loaded the command.
