Old lady fishing shack SPOILER

[cut_lass]

I got the shivers check at the Old lady's house. It told me to check under the floorboards.
But I don't know how to check. There isn't a clickable area,no floorboards get highlighted if I press Tab. It's the same as before
What am I missing?

Please help :(

Leave it for now. Not sure if it's intentional, but I couldn't check the floorboard until I came back while I was looking for a suspect on the coast.
