Trigger socketed spells recipe does not spawn in Refinery

After multiple runs of The Refinery area (approximately ten in total between myself and a guild member), the crafting recipe for “Trigger a Socketed Spell when you Use a Skill” has not appeared. Each run involved fully clearing and exploring the area to ensure nothing was missed.

The crafting bench indicates that this recipe should unlock in The Refinery, but it has not spawned in any of our attempts. Some other guild members already have the recipe unlocked, and there are plenty of items with this mod crafted on trade, suggesting it is still obtainable, but its actual location may not match the stated information.

I'm having the same problem and playing a minion build. Also for me the refinery does not reset on a fresh instance. Only the quay fully resets. All ground loot and the map fog cleared are present on reset.

Edit: I missed the change for hidden room.

Can confirm I got the recipe from Refinery like day 2 of the league. Same sewer drain it has been in since the changes.

That said, I do wonder if the league mechanic maybe eats the sewer drain if in range. Assuming the instance owner is not overlevel to prevent it from spawning.

I was having the same issue. Sewer grate was there but wasnt marked.
