No error message. Can happen with only Bewitchment. Server complains about being [insert number] ticks behind.

Last commit in used build: 9270a19

Steps:

• Create a default flat world in creative mode.
• Upon spawning, teleport to 0 60 0. Do not be in flight mode.
• Wait until you hit the ground.
• Run /time set night immediately
• Wait and look around, the entities will eventually cease to move or function for a variable period.

Details:
Skybox continues to move.
Updates between server and client cease to function.
Server stalls, client remains fine.
Computer burden appears to be negligible.
Client can move and attempt to interact during period.
Depending on burden before period, periods unrelated to burden may happen consecutively.
Happens in singleplayer and multiplayer.

Has been reproduced with earlier build, might not be a recent bug?

Has been produced outside circumstances outlined, might be an entity-related thing?

Has not been reproduced in vanilla.

I was loading 24 chunks. I have a hunch it may have to do with the ghost entities, or other hostile entities.

HAS NOT BEEN REPRODUCED WITH DAY-TIME ENTITIES IN FLAT WORLD ENVIROMENT. (Such as cattle, slimes, etc)

UPDATE:
I believe I have isolated this. The above scenario does not work if the world is in peaceful.

Given this, it obviously has to do with hostile mobs or a conditional relying on non-peaceful mode.

Because of said conclusion, I believe the ghost entity is the responsible party.

Ok so yeah its the ghosts. This is me using my fork that just guts the ghost entity.
It no longer freezes with the above conditions, and it also doesnt freeze if I add bewitchment mobs and then do the above conditions.
