Stuck in The Hero of Gavel quest

Hiya.

I got to the end of the Hero of Gavel quest and am up to the part labelled???.

However, every time I spawn in Seigfried just despawns and the quest doesn't progress.

I tried /class (as I had to do a lot during the quest) and I even tried /kill and made my way back to the temple, with neither of them solving the problem.

I'd love to finish this quest, so any help would be great.

Thanks

I went to the hub and rejoined the server from there and it fixed itself.

Thanks anyway!
