Update: I was wrong about one thing. When trying to dialogue with NPCs other than Sven, it's not always the player/MC reporting the issue. I am not sure how accurate this is, but I noticed whenever I try to initiate the dialogue from the counter, the NPCs avatar shows up and reports the issue, but whenever I reach behind the counter to get closer to them (I almost always do that to make it easier to trigger the dialogue), then it is always the player that reports the bug. It could just be a coincident though.
