Sun doesn't set, villagers move jerkily, bow and arrow sluggish

Playing Minecraft Bedrock Survival on a newish Windows 10 laptop. Multiplayer world is on a server at Shockbyte. Villagers are moving more slowly, with periodic jerkiness. The sun also doesn't set, creating a kind of twilight Groundhog's Day. Sunset animation will start and stop around 5-6 times before setting.

Was trying to shoot a creeper at medium range with a bow and arrow. All arrows were falling way short. Other weird slowness like experience orbs moving more slowly and freezing.

This started roughly last week, after I had converted a village of zombie villagers to the living life of productive citizens.

I've been playing this word since January. Experienced a similar problem back in December with another long term world, same server, same configs. Village got laggy over time and then I could log in, move around for 10 seconds and then the world would crash. I started this world because I didn't have a good backup of the 2020 world.

I will clip my stream tonight which shows the issue.
