Command blocks not always outputting text/commands

Build: #339699 and #341726

Impact:Stops command blocks from running. This breaks the map as items aren't always given and text/voiceovers aren't always played.

Repro Steps.
Unclear. Happens randomly. Video will be provided in the next day for a better example with out map. Please contact me on slack for a copy of the Map.

Observed Results:
Command blocks not activating at the right time. This issue can be fixed sometimes by saving and quitting and reloading the map.
