Preventer
A mod that prevents you from doing dumb things by accident.
About this Mod
Preventer
Preventer is a collection of over sixty modules who prevent you from doing certain actions (e.g. accidentally breaking budding amethyst or stripping logs).
Each module can be enabled or disabled individually in game via a config screen (press I) or all modules can be temporarily disabled with the Override Key (hold R) .
If you want even more control over what actions are blocked, check out Action Regulator which allows you to create custom rules for blocking any action in the game based on a wide variety of conditions.
