Sometimes when I teleport players to different worlds on my spigot server, the client crashes.

I'd say it's about a 10% chance and so far it has occurred on two of my worlds, again, with seemingly no pattern.

The server is still on 1.15.1, but I assume it still holds true on 1.15.2+, as such, the crash report might be outdated, but it is the best I have at the moment.

When the crash occurs I get the "Saving World..." screen for about a second, right after loading the world, and then the window closes.

If it is necessary I can post the world files as well.

Also as a little note, both the worlds that the crashes have happened on, have a lot of traffic (people going back and forth), and both worlds are void worlds with things built around 0, 0.

Edit: not a resource pack problem, as I have completely different resource packs now, but the problem persists
