I cant interact with the window in the Whirling-in-Rags (Day 8)

Hey guys, Kim keeps telling me that I'm missing something with the deserter. Unfortunately I don't have a motive yet. I know that the solution is in the secret passages of the Hotel since Ive done everything else. But for some reason, the window in the Hardy booth isn't interactive for me? It was at the begining (but it wasn't time back then). Did I wait too long? Don't really want to start over from the save before the tribunal tbh.
