LastException during travel: VehicleLiabilities.py error

Product and Version
The Sims 4 (PC/Mac) — Patch 1.118.257.1220

Platform: macOS (Apple Silicon / Metal)
Mods/CC Installed? No. This occurred in a vanilla game with no Mods or CC.

Issue Summary

The game generates repeated LastException logs referencing vehicle_liabilities.py:307. The error states:

AttributeError: 'NoneType' object has no attribute 'can_transition_over_node'

I did not receive any in-game LastException popup, and the game did not crash, but I did notice slowdown and slight glitchiness before I found the logs. Since this occurred in vanilla, I believe this is a core game issue.

Steps to Reproduce

I do not know the exact trigger. I was playing normally in a new save with the latest pack installed when the slowdown and glitch occurred. I later discovered the LastException logs in my Sims 4 folder.

I suspect it may occur when Sims/NPCs attempt to use vehicles, or during routing while traveling/entering a lot. Exact reproducibility is unclear.

What I Expected to Happen

Sims should route or travel without generating errors.

What Actually Happened

The game produced repeated LastException logs (attached). The error trace shows a failure in vehicle routing logic during _get_close_to_deploy.

Error Trace Snippet (from log)

File "T:\InGame\Gameplay\Scripts\Server\vehicles\vehicle_liabilities.py", line 307, in _get_close_to_deploy

AttributeError: 'NoneType' object has no attribute 'can_transition_over_node'

Frequency

Happened multiple times in one session. Generated several LastException files in the same play session.

Note from EA_Solaire:

    Three exceptions in one gaming session. Not entirely sure if I had mods earlier in this save, but definitely didn't when the exceptions occurred.

    Do you have one that isn't from a modded game ?

    Bug forum is ONLY for issues tested on a vanilla game.

    This has just happened to me. I do have mods installed. My sim was on their home lot with no travel action queued.
