The steerable wheels on trailers will rather be in an new oversize trailer DLC, maybe licenced.

So maybe it's related to where the Promzona fix is located in the loading order.
I've put it at the very top of all map files

Ok I made a ferry-train trip to Vorkuta then Labythnangi to Severomorsk and then Severominsk (both by ferry- boat).
No crash and no missing snow textures.
This with Sgate weather mod by Blackopen.

Frachti, in the past I had only black textures here and there without the snow-fix but never a crash.
The loading order with Promods and other maps has changed, right ? (ref : ROS readme text)
Now the ROS files should be on top when they used to be at the bottom when using other maps.

Just started a new profile and I don't have enough xp to go straight there so just moving slowly eastwards one mission after the other.
Currently going to Obninsk in Rusmap.

@RikkiBobby13 I 've got those ferry related errors : " Missing target link for ferry destination (kdop_link.ferry.nadim) " ditto......................................................(kdop_link.ferry.v10) Maybe that's the one you've been writing about. Edit : riding the same maps as you. Na...

Do you use a weather mod ?

It would already look better without the black plastic side panels that make the cab look shorter than it is.
It seems like it's an option.Saw one yesterday btw .

Yes, unexpected frontal crash with incoming truck for me there

Those traffic mods are fully compatible with Jazzycat's traffic packs and trailers and cargo packs if it is what you wish to know.
