Describe the bug
Walking around and exploring the overworld the game locks up. The log files may indicate pmmo is a problem.

Expected behavior
Walk around and explore without the game locking up

To Reproduce
Steps to reproduce the behavior:

1. Walk around the world
2. Game locks up

Screenshots
If applicable, add screenshots to help explain your problem.

Versions:

• Minecraft: 1.20.1
• Loader: Forge-47.2.20)
• PMMO: 1.20.1-1.2.19

Additional context
latest.log

Two things.

1. nothing in this log mentions pmmo as throwing an error
2. Forge added breaking changes in 47.2.x I would roll back as far as you can to get out of the .2. range. Preferably 47.1.3 since mods that work on that version are compatible between Forge and NeoForge.

The latest log must of got archived. Here is the relivant error

[12:09:09] [Worker-Main-65/ERROR]: Async chunk load took way too long, this needs to be reported to the appropriate mod.

okay, so the error is that the structure took too long too long to load. Could you run a spark profile on this so we can see where in this stackttrace the delay is happening?

Ok, will try an capture the issue with Spark

Another user was having a similar issue and found it resolved when they disabled Levelup Unlocks in pmmo-client.toml. you might try that and see if your issue resolves.
