The Delve Shadow Enclave with the cauldron story is bugged. There are only 2 items to sabotage the northern cauldron but 3 are needed.
Jump on the mushroom
I was on all mushrooms, still found 2 only.
I had to reset my run because if you drop off two ingredients at the same time, they only count as one, so I was one short.
I had a bug where the item was on the ground but I could not pick it up. I tried reloading but no go.
Ive had a similar experience where the Frog rare spawns, there is usually a boot on the ground there. When picking it up it drops and disappears or drops and when you try to pick it up it again it disappears. You use the jump mushroom to get to it, for the North Side cauldron.
Yeah this delve is a stinker. Its the Infiltrate and ameliorate story. Half the ingredients cannot be clicked, and most of the others just don’t do anything. I spent an hour in there, read some guides, then gave up.
Personal blacklist for this one.
