My confusion arose from the codes wording for duplicate UTs. “The no-duplicates rule applies to unique treasures only during setup, when placing them in the treasure pool.” This made me think that the treasure pool is where they had to be unique. Thought I’d just verify it here, thanks again.
Even with the potential to be cancelled, there’s not really a defined “front” or starting point for the tentacle placement, and all the slots are the exact same size, so the exact positions don’t matter. I’ll add a line saying that to my notes for the possible future update.
