2015-06-13 20:24:36 [FINE] [ForgeModLoader] MLProp configuration file for mod_MMM_MMMLib found but not required. Attempting to rename file to mod_MMM_MMMLib.cfg.bak

2015-06-13 20:24:36 [FINE] [ForgeModLoader] Unused MLProp configuration file for mod_MMM_MMMLib renamed successfully to mod_MMM_MMMLib.cfg.bak

 

No error what so ever, cfg is replaced 100% of the time for no reason.

 

Someone explain this nonsense to me.

Even the source code makes no freaking sense, mlPropFound is always set to true.

The version doesn't matter, if it happens in 1.6.4, it's gonna happen in newer versions.

I want to know why this happens.
