I have tried to edit the recipe for the wind turbine but it does not update the recipe in game even when I use 'game.player.force.resetrecipes()'.

Is this because of how you save the current game content?

How can I get the recipe to update?

I will attach a zip file containing my mod. Here is the error I am getting:

Path
__BetterWalls_0.1.0__/graphics/entity/steel-gate/gate-base-horizontal-mask.png does not match any mod.

Any help figuring out what this error means and how to fix it would be greatly appreciated.
