ToME: the Tales of Maj'Eyal

Just cleared a living weapons vault in the Hafling Ruins as a Thalore Cursed, and found two copies of the Poltergeist Bloomsoul Mindstar, even though the game claims it's unique (which I assume means you can only ever find one in a single playthrough).

This is known and an MR with the fix to this already exists, so prolly will be fixed in the next patch.
