i solved the problem of the broken vehicles. it was cause of an mod

No problem, you're not Gorkovskiy Auto Factory, give yourself a rest.

bad news, i have an new pc, and the saves arent cloud saved, soo all of my contraptions are gone, and subscribing to my own contraptions dont work, cause most of them are corrupted, i cant build or improve vehicles, like this one , but im getting sent the local files thru email, and if that doesnt work then i wont be making vehicles for an while

aww. no problem

Thank you for all of your brilliant stuff
