Start with the hydration indicator
First confirm that hydration is active in your build. If the expected meter or mechanic is absent, check the mod version, configuration and whether another mod is replacing the same system.
Use version-appropriate water interactions
Different releases can change how natural water, containers or purification mechanics behave. Test in a fresh world and use the controls or items documented for your exact build rather than assuming every release is identical.
Plan travel around refill opportunities
Treat water access like food or shelter: carry appropriate supplies, note safe refill locations and avoid long routes when your hydration is already low.
