I feel like a major noob, but no matter what I put in info, the harvest levels of blocks do not change. My config:

Do you have HarvestLevelTweaks disabled?

I implemented the config, and I can still break the blocks... :/

If you have the HarvestLevelTweaks module disabled it wont work because of a bug. If it's enabled it should work just fine. If it doesn't work your config probably is broken.
This here worked perfectly fine for me: http://pastebin.com/ga4gvHzq

Well, you could start off by reading the huge comment at the top, and by throwing a look into the default-file to see how you're supposed to do it.

FACEPALM

Very sorry, I can't believe I didn't notice that... that's what I get for skimming

BTW, this is an amazing mod you got here, even if it's a remake of an old one, it's still a marvelous modpacking tool, I don't know what I'd do without it.

Got it working? :)

Just fixed the config, trying it out now

Um, the game just turned the config into the default override config...

This:

Turned into this:

When I booted up the game... I think I'm missing something T_T

Because the game doesn't care about info. Info is for the user, not the game. :P

Literally all you have to do is copy your stuff out of the defaults and adapt it.. that can't be too hard.

So if I'm understanding this right I should make it as so:

Yes. It literally says so in the huge comment at the top. The very first thing.

I'm really sorry, but somehow even that didn't work, that exact file was overridden when I launched the game

And even downloading the latest Zip won't fix it?

Yeah, I think my config is broken, any idea on how to fix it?

There are no zips. Next release will fix it.
