Hey,

just like the issue I had with the mod "Chunk-Pregenerator" the config file of this mod is also reset incorrectly by forge.

Every few restarts we have a backpack on the server with only one row because this is set as default in the mod and the config is reset to it.

backpackInventorySize = 1

[Thread-0/WARN] [net.minecraftforge.fml.config.ConfigFileTypeHandler/CONFIG]: Configuration file /home/mch/multicraft/servers/server240349/config/backpacked-common.toml is not correct. Correcting

Minecraft 1.19.2
Mod version 2.1.10
no Notepad++
File edited when server was offline

Errors from my side have already all been excluded. After all, it is only a change of a number from 3 to 1.
The problem already occurred after the installation when we suddenly had only one row in the backpack after a restart.

The creator of Chunk-Pregenerator released a patch for this very promptly and switched to a different config system.

Night Config Fixes has a fix for this now after an Update.
