The game crashes with segmentation fault error on movement.

Nobody has claimed this yet.

### Describe the bug

Hi. It does not have stable reproduction steps, but once in several hours when I do a trim on my car to already visited area the game crashes with the Segmentation fault error. Crash.log file is in the attached save file.

### Attach save file

There is no stable reproduction steps, just occasionally the game crashes when I travel on car to already visited area.

No crashes.

### Additional context

_No response_

Start by loading the attached save file and reviewing its crash.log, then try traveling by car and trimming an already visited area on the reported Windows and SDL3 configuration. Done means the segmentation fault is reproduced and its cause is identified and fixed, with the same movement scenario no longer crashing.
