Missing...
combat_bonus.json,
mining_bonus.json,
craft_bonus.json

on create in /config/levelup2/json/skills/{skill_name}

I get NoSuchFileException for these files, can I safely create empty files?

The error is not if a skill's hasExternalJson in loadFromJson:

The exception doesn't really affect anything, but I think a blank json file should silence it.

It does. Thanks, I'm just trying to clean up my logs.

I ended up leaving those out of configurability, since they only really provide experience bonuses that don't break the game that much.

@BeetoGuy I guess those files are already in the source code, added by c6493a2 , why won't you compile it and release a mod jar with this fix?..

There are several factors that had me step away from modding for a while. I'm looking into adding a few things before pushing a new fix, now that I'm beginning to get back into the swing of things.
Edit: It seems the fix has been live on CurseForge for about a year.

Could we please fix the console spam from this?
