I'm trying to change the harvest level of all logs to 1, but I crash on startup with all the possibilities I've tried.
The crash is nearly always the same:
https://gist.github.com/NillerMedDild/91ec0e388d8f7f6ae3d4d74b9feb9717

I've tried a lot of different ways, here are some of them, all tried one at a time:
minecraft:log=1
minecraft:log=1-'axe'
minecraft:log=1-axe
ore:logWood=1
ore:logWood=1-axe - unique crash https://gist.github.com/NillerMedDild/2654599c00cac48598cf653d511b134a
ore:logWood=1-'axe'

The first crash is because you arent setting a metadata for the block id, you can use ":*" as a wildcard. I can also look into making that not require meta at all.

Not 100% sure about the oredictionary one atm, I'll have to look into that one.

Ah, thanks! I'm not used to this kind of config requiring a meta, but I don't mind. I just noticed the :meta in the syntax explaination above ^^'

Sounds good.

The game is able to launch just fine now, but it doesn't seem like the harvest levels of Logs are actually getting changed. I'm able to break Oak Wood with an empty hand, aswell as a Tinkers' Wooden Pickaxe. Here's the config:

S:harvest_level <
minecraft:log:*=2-Axe
minecraft:log2:*=2-Axe
dynamictrees:oakbranch:0=2-Axe
dynamictrees:darkoakbranch:0=2-Axe
dynamictrees:birchbranch:0=2-Axe
dynamictrees:sprucebranch:0=2-Axe
dynamictrees:junglebranch:0=2-Axe
dynamictrees:acaciabranch:0=2-Axe
dttraverse:firbranch:0=2-Axe

Could be because the tool class is capitalized?

Changing Axe to axe didn't change anything sadly. Could it be because it doesn't require a tool by default?

Nope, it's still harvestable by anything.

It would appear the meta wildcard * doesn't work either.

If you don't put a required tool does it work? Or putting 'null' as the tool?
