StyledPlayerList

StyledPlayerList copied to clipboard

I am using Fabric server, and I add StyledPlayerList and Carpet mods. After I starting my server with save has Fake Player datas(include in fake_player.gca.json), however server crashed once fake player joined like below:

[08:23:56] [Server thread/INFO]: End joined the game
[08:23:56] [Server thread/ERROR]: Encountered an unexpected exception
java.lang.NullPointerException: Cannot invoke "eu.pb4.styledplayerlist.config.Config.isPlayerHidden(net.minecraft.class_3222)" because the return value of "eu.pb4.styledplayerlist.config.ConfigManager.getConfig()" is null

And I found that the contents of fake_player.gca.json have been cleaned.

I re-imported my save, and disabled StyledPlayerList, server started successfully.

I checked the source code of ConfigManager.getConfig(), it might be StyledPlayerList can't get config for a fake player.
