Spreadplayering Long Distances Crashes Client

I'm spreadplayer-ing instead of teleporting myself and others 1024 blocks from spawn. I'm using the spreadplayers command like a teleport because it loads the chunk for the player so they don't glitch through things when they start.

My lobby is a large distance from my spawn chunks. It's hard to describe what happens, but:

In Spawn, Spreadplayers to an unloaded chunk far away from Spawn. Client crashes.

Relog, player position has updated and I am now standing ~1024 blocks away.

Spreadplayers BACK to spawn, which SHOULD be loaded, but doesn't have anyone in it ATM.

Client Crashes.

Relog, player position updated and am now back at spawn.

Continuing with the problem.

While in

I do not seem to be kicked when I do not have my F3 coordinates on.

As soon as I toggle F3, the game crashes.

From 1024 1 0 I teleport back to 0 1 0, and toggle F3. No crash.
