Let me know if you need savegame to check it too.

Save game, and sliders values used for the engine would be helpful. Thanks!

Engine designed is Truck6, with Chassis Truck5 and Gearbox Truck5.
I tried multiple car types, with few clicks all generate negative numbers.
Save is https://drive.google.com/file/d/1S00vLG0S731xPiStd7_JZP1OyR_JsShg/view?usp=sharing

Thanks, I'll have a look at it sometime next week, as I am in the process of getting v1.25 RC2 rolled out right now.

I think I have the issue fixed. Should be in the next update, be it a Hotfix or v1.25.
