Unsolved 96 Pessima Expansion Pack

Hello!
As a lover of wagons in BNG I want to ask if anyone has a fixed version of this:
https://www.beamng.com/resources/96-pessima-expansion-pack.12895/
Or either the wagon or the hatch

Also if mods want to take this down for being off topic do it

 

I also want a fix for it

 

I think KLJP is working on smthng like this

 

hmm interesting

 

Can you post a photo if kueso or LJ posted one?

 

I wish, someone told me about it in another thread, and I cant find it
