By encouraging the user to use the in-game trailered item mechanisms, this script mod improves the game. Wheat and hay are examples of loose items and crops that will fall out of trailers when they are going too rapidly or topple over if they are not covered. The speed, mass, and present weather may all affect how quickly you lose your belongings. But be careful—the cover can shatter if the trailer tilts over too far or if the weather becomes too bad!
Caution
Since this mod is still in its experimental phase, flaws and issues could arise.
Situation
All fill kinds are affected by wind loss; at the moment, rigid body trucks and vehicles with tipping configurations (CV, Tigre, etc.) are not functioning.
At this moment, tilt loss is not used.
Identified Bugs
Each vehicle emits fix particles when fillUnit > 1 (all share the last loaded shape node).
Automobiles and trucks with fillUnit setups don't experience any loss or impacts.
When cleaning up particle effects when active, changing systems stop emitting (possibly related to #6) and the player or AI moves too far away from the source, preventing them from reappearing when returning in view. This crashes with a lot of active windloss and particles, requiring the user or worker to have active selection on the trailer or implement when operating a vehicle for windloss to occur.
