W900 Semi-Truck Mod
Version 1.4 Player Summary

Version 1.4 focuses on cistern gameplay, hydrant rules, and cleaner bogie tire behavior.

Key gameplay changes

- The cistern now properly supports separate gasoline and water tank setups.
- Water can now be filled into the cistern from hydrants when you have a rubber hose.
- Hydrants are no longer infinite after the world water shutoff. Each hydrant now has its own limited remaining reserve.
- You can now check hydrants with the context menu to see whether they still provide unlimited water or how many liters are left.
- After shutoff, hydrants only work when they are actually still supplied, including valid nearby generator support.
- Empty 2000L trailer tanks can now be converted between gasoline and water variants with a mechanics recipe.
- Fuel and water interactions are now much stricter and more reliable:
  - Water only goes into the correct water tank.
  - Fuel only transfers from a valid installed gasoline tank.
  - The tanker refuel option no longer appears for invalid tank setups.
- Gasoline and water tank variants now correctly block each other during installation.
- Split cistern tanks can only be removed when they are empty.

Driving and maintenance changes

- Rear bogie tires now behave more naturally and no longer force shared air pressure.
- Tire damage on bogie pairs is handled more fairly instead of constantly mirroring both tires.
- Replacing one tire on the bogie no longer drags the fresh tire down because of old sync behavior.
- Wheelchain behavior on bogie pairs has been cleaned up and is no longer forced into unnecessary shared-state handling.

In short

- Cistern gameplay is more consistent and much harder to break.
- Hydrants are now a real limited resource after shutoff.
- The W900 rear bogie setup behaves in a cleaner and more predictable way.
