Kamulton no this mod does not effect berries, or fruit trees. both of those would require .dl creation to change their growth. this mod is only a patcher mod, which would allow it to be cross compatible to future versions as long as they don't change any of the crop/*.json files.

Do berries ripen faster with this mod?

TheUSDoctor No you should not need to a new save.

do i have to make a new save for this mod to work?

Vigilance true that its possible to use the worldconfig to do so, but not everyone wants to take the time to change that setting everytime they create a new singleplayer world.

Vigilance A lot of mods introduce the same config edits that can be made manually, like Higher Clouds, VSAtlas, etc. The point of mods like this (and there are others that do the same) is the ease of not having to load a world just to make the adjustments.

Isn't this already a world config? Per the wiki:

/worldconfigcreate double cropGrowthRateMul [0.1 ... 10] "Sets the growth rate for crops and berry bushes."

This mod need a description
