I just updated to the latest version of the game on Windows 10 (0.9.10) and went to check Rafaelo & Arthur but the seller affinity gauge is empty even though i've already bought everything from them in the previous version of the game, I tried in the morning and in the evening but it doesn't change anything, haven't tried at night but their shop are closed (the library is still open because I got the key) last time I played I was on version 0.9.8.2 but I don't remember if the seller affinity gauge was full or not since I wasn't coming back to their shop anymore
Edit : I think it's doing the same thing with bandit since I bought all underwear he sold but it's still empty, I bought one more and the gauge started to fill
