wat.
When a map changes for whatever reason and is re-uploaded, the online score table will change to a pulsing "update map" (IIRC) button. You can click that to update that map, but sometimes game assets (the audio file, the background, or parts of the storyboard, for example) change and they are
not currently updated when you update in-game like this. If you're paranoid you're missing out on some of the updates, you can re-download the map. (You can type /np in chat to get a link to the map, or click the web icon near the score table.)
I think an upcoming feature (osz2) will make updating smarter, so keep on the lookout for osu! updates if you're really annoyed by the current solutions.
