[Fabric 1.20] Map state doesn't update unless a shutdown occurs

[mookman288]

Hi.

First, thank you @granny for taking over the Pl3xMap repository and providing us a space to reach out for support. Thank you to @BillyGalbreath for Pl3xMap and all of the work you've done to provide the community with such a stellar plugin.

The issue I'm submitting today is related to the map state not updating unless a shutdown occurs. Changes to the map, the fog of war, or anything related to map state, does not update unless I perform a full shutdown. A simple reload, or save, does not allow the map to update.

Server: Fabric 1.20
OS: Windows 8.1
Java Version: 21 LTS
Tunnel: I am using a vLan to allow access to the server and the map, so it's currently not on the Internet--but checking the map directly from the server does not update either.

User status and location updates in real time.

I noticed nearly identical issues with another plugin, Fastback. You can read my issue for that plugin if it can provide any insights. Fastback performs incremental backups of user and map data. All user data is updated regularly, but map data does not update unless I perform a full shutdown.

Based on the fact that other plugins are mirroring this issue with map state, I imagine that this is related to an issue with how plugins, like Pl3xMap, access map data. I need to eliminate Pl3xMap as the cause before I reach out to Fabric. Therefore, I am hoping someone from this community can lead me to what exactly occurs when Pl3xMap wants to read map data.

Is this a Fabric API issue? Complication from another plugin? Is it something more intrinsic to Minecraft? Is there a setting somewhere that needs to be enabled to allow Pl3xMap access to map data in real time? Permissions issue maybe?

Here are the only relevant logs that I could find:

Thank you for any insight you can provide!

There were a ton of builds and changes since 1.20-443. There's a good chance that your issue was fixed on builds made for a newer version of minecraft (Fixes that are available on 1.20.1 did not get backported to 1.20, for example). However, there is a chance that the current 1.20 build available on Modrinth may fix your issue. If it doesn't, then there's nothing else I can really do for you, unless you are able to reproduce that issue with the most recent 1.20.2 build.
