Can you explain that in more detail? I've never even heard about those. What would be needed to support this use-case properly?
Pre 1.6 the only way you can edit .lang files is to edit the ones in the .jar, this was changed 1.6 onward so that you change it in a resource pack.
The instance I am trying to play on is in 1.4.7, its an instance I have had for quite some time now, it has alot of mods on it aswell as a tweaked .lang file.
The problem is that MultiMC v5 keeps regenerating the META-INF folder, and the META-INF folder resets the .lang files, making the custom .lang file not work. This has never happened to me in v4.3
Since theres no resource packs in 1.4.7 I cannot simply put the lang in a resource pack, I have to edit the .jar and the regenerating META-INF folder makes that impossible.
