I've been working on adding proper doors to some of the AI chase vehicles (Black Ferrini, Milk Truck, etc.) and the Milk Truck especially has been extremely stubborn because my modified .p3d absolutely refuses to load in game. I have triple checked the .p3d several times and I cannot find anything immediately wrong with it, yet no matter what I do the game crashes every time when I select it from the phone booth. It's the same error every time too, from what I can tell from each log (using the Consoles and Logging hack):

[2025-06-26 15-44-12.361] Exception 0xC0000005 (access violation) at Simpsons.exe+0xF08E6 (0x4F08E6) reading 0x6.

I have tried deleting, rearranging, renaming, and even remaking the .p3d over a different vehicle, as well as trying to give it a separate filename, index, and vehicle ID. None of which have worked. I am completely stumped by this.

Here is the p3d, log, and crash dump, for anyone who can view it.

Seems to be an issue with Vehicle::AddFlappingJoint - I'd have a look at the vehicle's skeleton in comparison to others. Aside from that, no suggestions, sorry.

mazzy Hi there, it seems that your `cMilk.p3d` file has `Skeleton Joint`s for the flapping doors, but no `Physics Joint`s and `Collision Volume`s. (https://mega.nz/file/sgcGVIhD#kAMOFPQbQpEYvWLmY3U7rMzmjfzP

Hi there, it seems that your cMilk.p3d file has Skeleton Joints for the flapping doors, but no Physics Joints and Collision Volumes.
Here is a fixed version of your file.

I suggest you check out the differences between the file I uploaded & yours to see the changes other files might need. If you wish a more in-depth explanation of this, let me know!
