ticks.json simply ceases to function randomly

Partner Rank: 1

Verification builds:
1.16.200.2

Summary:
ticks.json simply ceases to function randomly on PS4 and Win10

Impact:
makes maps using ticks.json unreliable and unplayable randomly and without notice

This affects multiple community celebration content.

Simburbia
TSF

Repro Steps:

Open Simburbia

Play until time stops and the game becomes unresponsive

I have not been able to reproduce myself, but I have gotten a number of reports of this occuring, mostly on PS4 but at least once on Win10

Observed Results:
^{In game time will appear to stop. Menu will not work, players cannot choose a speed. All game logic ceases to function.}

Expected Results:
Game should run as normal.

Screenshots/Videos attached: This is the only video that I could find of it occuring live. https://youtu.be/-Dgc-NtpM8o?t=2582 is when we notice it is broken, but it appears to break around 37 min mark here https://youtu.be/-Dgc-NtpM8o?t=2261

Regression Build:
unknown, maybe forever?

Notes:
This is a tough one, I have been unable to get a copy of the world where this occurs, but it happens often enough that I am reporting it and it affects a number of players. I have attached a number of comments to this as evidence of platform.
Things I have been able to verify:

• Closing and opening the world didn't fix it.
• copying the world didn't fix it.
• all the entities are still in the world
• I can only suspect it is ticks.json that is failing based on the video evidence that I have seen.
• no steps "before it happened" have been consistent, indicating it is randomly occuring
