Unblanced weight

[Ekan]

Hi

I converted a liguid manure from 11 to 13. Most works good but for some reason the trailer puch the tractor down. When u drive straght ahead the trailer puch the tractor down and when I drive backward the trailer lift the tractor. Even with 2t weight nothing happens. I asume there is something in the xml file that need adjustment but I dont know what, ive tried with downforce and brake force but its sill acting the same, any helpful soul know what the problem might be?

Here's the xml:

Open the manure vehicle i3d in the giants editor and click on the main root of the mod and click on rigid body tab and look at the number for mass. I think if that number is too high it might cause the issue you are describing. I could be wrong but, thats where I would start if I understand your problem correctly.

I believe they changed the physics from 2011 to 2013 so some mods are off in the mass/weight thing.

I usually compare a modded vehicle with a default vehicle from the game folder and see how they differ and try to figure what is wrong.
