Yeah, that’s a strange one Drakkhis will need to look at on return.
What I can see though is that is a pattern loaded for someone that is not a Seamstress profession, because it is a much harder puzzle than what the Seamstress would get. The Seamstress gets a 3x3 puzzle for this material.
It could be that when the puzzle tried to increase complexity for someone not of Seamstress profession that something in the backend is causing a small bug we will need to fix.
We are currently in discussions on how that will work.
I think a puzzle ‘one-off’ to discover a new pattern would be the way to go. Then you can choose to make it from recipes or open the minigame (so you can see the texture) and just craft without having to solve it again.
