from what I can remember and checked your right there aren't any heart events with Barrel rn, but because of that now I'm really confused and pretty lost on what could be causing this. I checked my save to see if we had any differences but the only difference is you actually have 1 more like than I do.
maybe it's what you've done with him during the events before? specifically what stuff did you do with Barrel during the other scenes. like when you check the like tab does it say stuff like "Barrel found out your willing to pay to play with Harold's gut.." or "you licked his boots" and stuff or anything else?
