Hard crash when reloading after dying in regulator fight

[Aussiemon]

SLOT02.zip

1. Arrived in Adytum by caravan.
2. Took mentants and leveled up.
3. Killed the deathclaws and deathclaw mother.
4. Told Razor I'd talk to Zimmerman.
5. Waited 4 days for mentat debuff to expire.
6. Returned to Razor without leaving the area and chose to fight without talking to Zimmerman.
7. Crash occurs whenever I try to reload the save (before 6) after starting the regulator fight. It's usually a hard freeze, but sometimes a "memory referenced unexpected location" popup.

Leaving the area and returning unfortunately triggers the missing Razor bug (I believe Vanilla).

From the debug log it seems still related to the caravan:

Script Error: scripts\carvlead.int: op_destroy_object: obj is NULL
Error: CombatData found with invalid who_hit_me!
