Carriage spawned but is completely invisible while NPCs repair it. No progress is being made - the spawn dialogue popped up in chat, but only the NPCs are visible and there is nothing to interact with. Invisible carriage, no progress so it won’t leave spawn in Korthia.
Edit: Happened into the Maw maybe 15 minutes after spawn and the carriage was actively going through the event. Made it all the way through finishing with Carriage Crusher… looks like it spawned and the animation just continued? But also didn’t give any dialogue that suggested it ever left spawn in the first place.
