description of the problem
I encountered a problem that when changing the "mysticalagriculture.cfg" file,

1)"mob chunk" are not disabled, when the parameter = false

2)The durability of the "Core Remover" does not change the number of uses, with a value of 1 (by default 4)

all other config parameters work...

to repeat
no idea

request
so that the configs work fully, a hint on how to fix it

Screenshots

• Minecraft:1.12.2
• forge: 1.12.2 - 14.23.5.2860
• Mystical Agriculture 1.7.5
• Singleplayer or Multiplayer: Multiplayer

So the first option is just to disable the recipes for the Mob Chunks, meaning you could only get them by killing the corresponding mob with a Soulium Dagger.

I just tested and changing the durability of the Core Remover to 1 was reflected after restarting the game. I'm not sure why that wouldn't have worked for you in this case.

I'm going to close this due to inactivity. If this is still an issue on the latest version you can reply here.
