I figured out your errors that you have I believe. You need to delete config out of the path. It should just point midwesthorizon/foliage and not midwesthorizon/config/foliage.
But I am getting other errors and warnings in the log too Some are for sounds and I can’t even find a sound folder in the mod. I’d have to look at it more when I get time to figure the other error and warnings out.
