Server crash duplicates from 13.01

[Händler]

Yesterday night the server crashed and I got my farmer gear exchanged for a duplicate of my intelligence gear. If possible, I would appreciate the duplicate int gear to be reverted to its farming counterpart.
I also lost a rock crystal that I used yesterday apparently. Both in w16.0

Appears we both have experienced this issue.
I am not too worried about the gear as I can make more but losing my Q364 scythe kind of annoyed me.

I just saw the charterstone is still there, which means the rock crystal was not lost.
However, one of the Knarrs that we built is gone, most likely because we built mould beds yesterday at the water and moved the knarr there and now there is frozen water at the spot with the knarr disappeared. I don't fully understand the mechanism behind it. The knarr is not in its original spot either, both of which were claimed areas. The knarr was half full of large chests, all of which were empty though.

Or was the Knarr perhaps removed intentionally?
