When i try the mod, or almost any wagon-mod for that part, the game just freezes and i get the vehicle error.
I just think it is wierd because, even with only the for example pessima wagon it breaks immidieatly as i try to spawn it :/
I don't really see how the Pessima Wagon could still be working, given the base vehicle was modified significantly a few months ago... If anything, body panels would be mismatched at the very least...
Might be more fitting to post the development of my gfx mods here than in the screenshots thread It took a day from the release of 0.18 until my fingers itched too much so now ive got a new mod on the go.

That mod has a good body and jbeam and such, and it adds cool new popups, but it's rear-wheel drive and takes up a separate slot.
About a month ago I tried to make the coupe into a separate body for the regular Pessima, and it almost worked, but I got bored halfway through and moved on to something else as I always do. Maybe I'll pick it back up.
So it turns out that like the LeGran, Miramar, and Grand Marshall, the Pessima was quietly remodeled with basically no announcement. I'm not exactly sure when, but that means that even the pop-up headlights don't work anymore (they do, but the hood and fenders don't line up). I did manage to work around that by porting the Pessima from 0.16 into 0.18, but now it's a separate vehicle. I'm going to try and rename every single part to get it in the same slot as the stock Pessima, but that's going to take a long time. The coupe body causes a fatal error, which sucks because I don't know how to use those to tell me what's wrong. (That's why my attempts to put AR126b's station wagon D-Series and Grand Marshal bodies on their new respective frames have both gone nowhere.) Additionally, just copying the Pessima's suspension Jbeam into the Pessima coupe's folder made the wheels glitch and spawn basically inside the car. Edit: Never mind, they mentioned the remodeling in the 0.17.0 devblog post, but like the LeGran, they didn't make a before/after GIF, and didn't even show any pictures of it.
