That's so weird! From the screenshot you sent it's almost like you tried showing Garret the soap? We'll have a look at this and see if there's a bug hiding there we need to fix. Thanks for letting us know!

I had this bug as well. It wasn't exactly showing the soap bar. For me I got the Garret sparing scene after handing in 5 node locations. I then proceeded to finish gathering all the stuff to save Warrick, and visiting Garret's shop he wasn't there. Interacting with his house/shop caused that popup to appear and crash the game.
Yeah Garret wasn't there at dawn/day/dusk after saving Warrick. Basically I did 5 nodes > Garret sparing cutscene > completed saving Warrick > Warrick was waiting for me to leave for Dragon Roost > I refused to check if I missed anything > Went to Garret's place and no Garret and interacted with his house > error message appeared.
