Unhandled ArgumentOutOfRangeException in Vehicle Builder on Linux

[Grug]

I am well aware that the vehicle editor is in a very early stage and is likely unstable, but I am providing the exception details in case this information is helpful.

​

Game Version​

2026.4.10.4057 Linux client (and several prior)

Operating System + System Specs​

Linux (Debian Forky/Testing)
Intel Core Ultra 5 245K
32GB RAM
NVIDIA GeForce RTX 5070 Ti - Nvidia open source driver v595.58.03

What Happened​

Building a vehicle and randomly when clicking somewhere - on a new part, or sometimes the Staging / Sequencing windows - the ArgumentOutOfRangeException is thrown.

What Was Expected​

The exception to be handled and not crash the application.

I have always had the occasional crash, but this seems to now be consistent. I have previously built a few multi-stage rockets with 50+ parts and not had it crash. Now it seems the max I can get is about 10 and I haven't been able to complete a single rocket and launch since this bug was introduced. I'm not 100% sure which was the last version that worked, but it has been an issue for at least a week now.

Reproduction Steps​

1. Start building a new rocket
2. Keep going until it crashes (usually less than 10 parts)
3. ???
4. Profit?

Reproduction Rate​

100%, but when is not consistent. Sometimes it happens after 2-3 parts, sometimes it is after adding 15.

Still the same for me, just for information:
