Auntie Ethel's Boon has no icon under "notable features". This applies to both UI setups. It just shows up as a black circle/square. Additionally, the controller interface has missing icons for backgrounds (e.g. Haunted One).

Came across an older screenshot from Reddit showing that this did have a proper icon at some point
