While slingloading on a dedicated server it is often the case that the rope will bounce back and fourth due to lag/desync. This often causes breaks in the line when there really shouldn't have been and you lose your precious cargo. It sucks.
In Mike Force with the new DLC, they have implemented a fix for this by making whatever is currently being carried local to the pilot - fixing any desync issues so you can slingload properly!
Can you guys add this to the base game of Arma so we can enjoy the ability to slingload properly across the entire game and not just Mike Force?
