The mod does not work on versions of the game above 46...
And at this point, I haven't figured out why yet, but I've figured out which direction to dig in. Wait for an update of the mod, but for now please do not use it, because there will be a bug when raising the key. You will lose all things. They will fall out of the inventory and you will no longer be able to pick them up, and also possible failure to game control.
