Maybe there could be a reward for completing the mod without using any of the hints THEN using the resources and time to unlock the hints after? Its a stupid idea but I think the mad lads and completionists would be happy, not saying you have to add it of course bc its kinda useless but hey, i cant think of a saying to put here

yes, why not. 👌

Better: these unlock automatically when the player get's to that stage.
